The restriction appears to be connected to Blizzard's earlier efforts to stop Treasure Breach and Path of Coin instances from being repeatedly reset for effectively unlimited Goblin farming. That exploit absolutely needed fixing. The awkward part is that months later, affected players say the solution still prevents perfectly ordinary trips to the Blacksmith and stash — even after the Goblin area has been cleared and its boss defeated.
Treasure Breach gives you a dungeon full of loot.
Then apparently asks whether you brought enough pockets.
A September Player Had to Leave Valuable Loot Behind
The newest bug report describes a Treasure Breach run where a Goblin portal appeared while the player's inventory was already full.
The obvious solution was to teleport to town, clear the bags and return.
Diablo IV refused.
The player entered the Goblin Dungeon instead, collected more loot and tried again.
Still no teleport.
They then cleared the Goblin Dungeon completely, including the final boss and its swarm of Treasure Goblins.
Still no teleport.
The result was exactly what you would expect when an ARPG showers a player with items while simultaneously disabling the system designed to store them: valuable drops had to remain on the ground.
The player later returned to the main Nightmare Dungeon, completed that as well and found that town teleport was still unavailable. Their eventual workaround was to physically leave the dungeon, teleport from outside, empty the inventory as quickly as possible and rush back before the instance closed.
It worked.
In the same way climbing through a bathroom window works when your front door is broken.
This Started With a Very Real Infinite Goblin Exploit
The current restriction did not appear for no reason.
Back in April and May, players discovered that certain War Plan-generated Nightmare Dungeons with the Treasure Breach modifier could be repeatedly reset without losing the modifier. As long as the final dungeon boss remained alive, players could clear the Treasure Goblins, reset the dungeon and run the same Goblin-rich layout again.
A separate Path of Coin interaction was even more exploitable. Players discovered that teleporting to town from the Goblin realm and returning could create another fresh instance. With the correct sequence of portals and dungeon transitions, the reward area could effectively be repeated over and over.
Players themselves reported these behaviours as exploits. One May bug report explicitly described the Treasure Breach as being repeatable “as many times as you like” provided the final War Plan boss remained alive.
That is obviously not what Blizzard intended.
Treasure Goblins are generous.
Infinite Treasure Goblins are monetary policy.
Blizzard Patched the Repeatable Portal in June
Blizzard addressed several related issues in Patch 3.0.4 on June 10.
The patch specifically fixed an issue where the Greed is Good portal could be activated multiple times in the same Nightmare Dungeon instance. Blizzard also corrected a Path of Coin problem where teleporting out and returning could leave the player unable to escape.
Those are real fixes to real bugs.
What Blizzard's notes do not explicitly say is that town teleport should simply remain disabled throughout Treasure Breach and Path of Coin content.
Yet on June 12 — almost immediately after the patch — players began reporting exactly that behaviour.
One player described being unable to teleport out to salvage the huge volume of gear, Seals and Charms dropping inside the dungeon. Another confirmed the same issue. A third pointed out an especially unfortunate interaction: an older bug could make the Curious Coin portal itself unusable, while the new teleport restriction simultaneously removed the usual workaround of going to town and returning.
Blizzard closed one escape route.
Sometimes the actual exit was broken too.
The Same Complaint Continued Through July and August
If this were simply temporary fallout from the June patch, it would not be particularly interesting in September.
But the reports continued.
On July 7, another player finally obtained a Treasure Breach Sigil, triggered the Goblin portal and discovered midway through the loot explosion that their inventory was full. They could not teleport out of the Goblin area, and leaving it caused the portal to close. They also reported being unable to town-portal from the parent Nightmare Dungeon while the Treasure Breach modifier was active.
The player summarized the problem rather neatly: the game was “raining down” loot while preventing them from collecting a large portion of it.
Another player confirmed the behaviour the following day.
Then on August 8, someone returned to the same thread to say the restriction was still present and argued that Blizzard needed to fix the underlying reset problem rather than maintaining what players increasingly saw as a “bandaid fix.”
Now it is September.
The bandaid has apparently developed tenure.
Treasure Breach Is the Worst Possible Place to Disable Town Trips
The restriction would be less absurd inside an ordinary dungeon.
Treasure Breach is specifically designed around an unusual concentration of Treasure Goblins. Blizzard's own Season 13 documentation describes the modifier very simply: a number of Treasure Goblins invade the dungeon.
Treasure Goblins drop things.
Rather a lot of things.
And if the additional Path of Coin/Goblin Retreat area appears, the amount of loot increases again.
That means the activity most likely to fill your inventory is also one of the activities where players report losing the ability to empty it.
It is difficult to invent a cleaner conflict between two game systems.
The Problem Is Worse Because Diablo 4 Has More Things to Pick Up Now
Lord of Hatred did not exactly simplify Diablo IV's inventory ecosystem.
Players now juggle ordinary equipment alongside Seals, Charms, Nightmare Sigils and various other progression items. Blizzard has made improvements to storage and loot filtering, but a dense Treasure Breach can still fill a character remarkably quickly.
That is especially true if the player is actually inspecting Greater Affixes rather than immediately treating every non-Mythic item as decorative gravel.
We have already seen how War Plans can produce strange friction elsewhere. Season 14 players have reported War Plans failing to recognize completed activities, while others remain stuck at Rank 9/10 despite finishing every objective.
Treasure Breach is a slightly different problem.
The activity works.
The rewards work.
The problem is physically getting the rewards into storage.
A Temporary Stash Would Solve Most of the Frustration
Players have suggested several ways Blizzard could preserve the anti-exploit restrictions without forcing everyone to abandon loot.
The simplest would be a temporary stash or salvage NPC inside Treasure Breach and Path of Coin areas. If players cannot return to town because leaving and re-entering risks recreating the old instance-reset exploit, bring basic inventory management into the instance instead.
Another option would be allowing town teleport only after the relevant Goblin encounter has been completed. Once every reward has spawned and the instance can no longer regenerate its Goblins, there is considerably less reason to prevent players from leaving and returning.
Blizzard could also make abandoned Legendary, Unique and other high-value items reliably flow into the player's missed-item stash, although that is less elegant when dozens of potentially useful drops are involved.
The proper solution, of course, is making re-entry preserve the completed instance without resetting the rewards.
That is slightly more complicated than putting a chest beside the boss.
It is also why game developers get the larger desk.
Stopping an Exploit Shouldn’t Turn Normal Players Into Casualties
There is no argument that the old infinite Treasure Breach behaviour should have remained in the game.
Players could repeatedly generate Goblins and rewards from content intended to be consumed once. Blizzard was right to close it.
The issue is what happens after an exploit has been closed.
If the protective measure also prevents ordinary players from using a town portal for months afterward, the exploit has effectively left behind a tax on everyone who never exploited it in the first place.
That is especially noticeable because Treasure Breach Sigils and suitable War Plan setups are not something every player sees constantly. Finding one should produce the pleasant Diablo reaction:
“Excellent, Goblins.”
Not:
“Excellent, I hope I emptied my inventory first.”
Five Months After the Exploit, Players Still Want Their Town Portal Back
The timeline is becoming difficult to dismiss as a temporary workaround.
Infinite Treasure Breach and Path of Coin loops were reported in April and May.
Blizzard patched repeat portal activation in June.
Players immediately reported that they could no longer teleport out to manage inventory.
The same complaint appeared again in July.
Again in August.
And now again in September.
The anti-exploit logic may be doing exactly what Blizzard wanted: players are certainly not resetting the Goblin dungeon by teleporting to town anymore.
They are too busy deciding which pieces of loot they can afford to leave on the floor.
