Howdy!
We are investigating players porting to older content, such as Class halls (Dreadscar rift for warlocks), other class halls(Priest/Paladins), or scenarios in legion for class hall/quests progress that takes place in Niskaras generate error 132 crashes. If this error impacts you, you can try waiting 15 minutes and then use the unstuck feature Here. We will update this thread once this issue has been hot-fixed. Until then, we recommend avoiding the Class hall or locations where you crashed.
Thank you.
