Diablo 4 Season 12 keeps finding new ways to jam its own progression. A fresh PC bug report posted on March 26 says the Den of Blood, Part 6 objective can fail mid-run, even when players are killing the required Bloodied Lair Bosses inside the time limit.
That is not just another small annoyance. This one hits a named progression step directly, and the player report is specific enough to sting: the counter can fail to award credit, or worse, roll backward instead of forward.
What is happening
In the report, the player says they were stuck on the objective to defeat 6 Bloodied Lair Bosses within 10 minutes in Torment 3 or lower. According to the post, some kills gave no credit, while others caused the progress to drop from 3/6 back to 1/6.
A second player replied the same day saying they saw similar behavior. They wrote that the game warned them the objective was close to completion when they were at 4 of 6, but after two more kills the tracker had dropped to 2. That same player later said the objective finally completed only after doing six more kills in a fresh run, without understanding what caused the reset in the first place.
As of March 27, the thread was still listed in Blizzard’s PC Bug Report index among current Diablo IV issues, which at minimum shows the problem has not disappeared from the active bug-report flow overnight.
Why it matters
This matters because Part 6 is not some decorative side task. It is a named step in a Season 12 progression chain, so when the counter starts slipping backward, players are not just losing time. They are losing confidence that the season’s own objectives can be trusted to track correctly.
It also lands in the middle of a season Blizzard has already been patching aggressively. The March 24 2.6.1 patch fixed multiple Season of Slaughter issues and said it addressed “various instances” where Season Rank Objectives or Capstone Completions did not grant expected rewards or could not be completed correctly.
Current status / what Blizzard said
So far, Blizzard’s latest official patch notes do not call out Den of Blood Part 6 by name. What Blizzard has confirmed is a broader sweep of Season 12 fixes, including objective and completion issues, plus other Season of Slaughter bugs tied to Bloodied systems and Butcher content.
The problem is that this report arrived after that patch. So while Blizzard has clearly been fixing season blockers, this looks like at least one progression issue may still be slipping through. That is an inference based on the timing of the report and patch notes, not a formal Blizzard statement about Den of Blood itself.
When the tracker becomes the enemy
Season 12 can survive hard objectives. It struggles more when the tracker itself starts acting hostile. If Den of Blood Part 6 is going to keep resetting progress in live runs, that is the kind of bug players remember long after the patch notes move on.
