Diablo 4’s Season 12 bug traffic is still chewing through basic systems, and the latest report hits something players do not usually expect to second-guess: boss keys. A fresh March 28 post on Blizzard’s PC Bug Report board says Bloodied Lair Boss Keys are being converted into normal Lair Boss Keys when picked up, instead of staying separate.
That is not just a messy inventory quirk. The player who filed the report said this is not about Sigils, but about the keys used to open boss chests, which means the problem cuts directly into how seasonal rewards are tracked and stored.
What is happening
According to the March 28 report, the issue appears when a player already has one version of the key in inventory. If they pick up a Bloodied boss key while holding a stack of normal keys, the Bloodied key can merge into the normal stack and lose its separate identity. The reverse also reportedly happened: normal keys stacked into Bloodied keys if the Bloodied version was already in inventory.
The player said a friend tested the same behavior and did not see the conversion happen, which makes the bug look inconsistent rather than universal. That may be worse in one sense, because inconsistent item behavior is harder for players to predict and harder to trust.
The report also picked up traction quickly. Blizzard’s PC Bug Report index shows the thread with 23 replies and 626 views on March 28, making it one of the more active fresh Diablo IV bug topics on the board that day.
Why it matters
This matters because Season 12’s systems are built around Bloodied variants being distinct, higher-stakes versions of existing activities and rewards. Blizzard’s 2.6.0 patch notes introduced Bloodied Sigils for Nightmare Dungeons, Infernal Hordes, and Lair Bosses, and said Bloodied content is meant to deliver stronger reward pressure than standard versions.
So if Bloodied boss keys are collapsing into normal stacks, players are no longer just dealing with clutter. They are dealing with uncertainty around whether seasonal resources are being preserved correctly at all. In a season already crowded with tracking bugs, reward issues, and progression blockers, that is a bad look.
Current status / what Blizzard said
Blizzard’s latest Diablo IV patch notes, 2.6.1 from March 24, include multiple Season of Slaughter fixes and general stability improvements, but they do not mention Bloodied Lair Boss Keys converting into normal keys.
So for now, the clearest signal is the bug board itself: the report is live, active, and not matched by a listed official fix yet.
Short closing paragraph
Loot games can survive balance complaints. What they handle worse is the feeling that reward items might quietly change into something else once they hit your inventory. That is the kind of bug that makes even routine pickups feel suspect.
