Critical Nightmare Dungeon Reset Bug

In Stage 3 of the Nightmare Dungeon, if you exit to a favorited town such as Temis (not sure if it works with other towns), then immediately enter the Seer’s Reach dungeon, open the world map, and re‑enter the Nightmare Dungeon you were progressing in, the dungeon content resets. This means you can continue again, with all gem chests, material chests, and other rewards reset and available to open anew.

It’s unclear when this bug first appeared, but it was very likely exploited at the start of the season. It doesn’t make sense that some players could use multiple Perfect Horadric Gems in such a short period of time without abusing this. This exploit is also possible in SSF (Solo Self Found) mode.

What I really hope is that Diablo IV will be enjoyed by a large player base and that the game will foster fair competition among everyone.

Steps to Reproduce:

  1. Enter a Nightmare Dungeon (Stage 3).

  2. Exit to a favorited town (Temis).

  3. Immediately enter the Seer’s Reach dungeon.

  4. Open the world map.

  5. Re‑enter the Nightmare Dungeon you were previously running.

Actual Result:

  • The Nightmare Dungeon resets entirely.

  • All gem chests, material chests, and other rewards respawn.

  • Players can reopen them and farm unlimited resources.
