It seems the increased loot at the end of Nightmare Dungeons change from the patch notes may have messed some things up.
Players are reporting simply not receiving the end of dungeon rewards at all. We’ve already seen the bug where the bubble and Glyphstone don’t appear, which was related to Rogues’ Barrage skill. That one was said to be fixed in the notes, but it’s still happening as well. However, this one is different. The following is just one example, but we’ve seen many players report simply not getting anything at the end.
A delayed bubble, and then an infinitely delayed loot popup. Hopefully we’ll se a fix for this one soon as well, as we’re less than a day away from Season 1’s start!
