Good morning, I was running a Nightmare 13 key and the last enemy in the Infested Laboratory- a requirement to spawn the final boss- was stuck in the wall and I couldn’t get to it or attack it. I ultimately had to abandon the run. It would have been my first clear of the dungeon and first nightmare 10+ run.
Please consider compensation for these bugs as well as an in-game bug reporting system that would allow players to report a bug to a game moderator in real time in order to potentially resolve these issues before runs are lost or forced to be abandoned.
