Spawning corruption boss might cause global server rollbacks for erveryone due to crash

We are noticing a lot of rollbacks lately but I think i have found the trigger.

I killed a rare very close to a wall or multiple walls which triggered the corruption boss spawn. The server immediately crashed and rolled back everyone.

I'm not sure if the positioning plays a role or spawning the boss in general but I thought this might help with investigations.


Edit: The corruption icon on the map (forgot what it was called) also disappeared after the rollback.

Edit2: I kept the loot from that map but the map now says attampted

I was walking to an exit with no mobs in site and rolled back. Was 30 seconds from end of Mattan Waterways... That map is cancer at the best of times but this is unbearable. I am out. See you when its patched GGG.
