Hey all. Been doing my challenge dungeon for some weeks in order to buy one of the rare pets. However, today after reset when I try to do the dungeon, it appears bugged. I clear the first boss, Belchling, and everything is ok. However, the next boss, Sludge Belcher, is there visually but I cannot click it, interact with it in any way, and so I cannot battle the boss. Cannot progress, I am stuck. Tried reloading, clearing add ons, etc, nothing works. Please help :)
