Copper Citadel bug

Hello,
I've had a very weird run on the Copper Citadel just now. I juiced a T15 map quite a bit, but absolutely no monsters spawned besides the Abyss and Breach. The bossfight with Jamanra was also bugged, Asala did not summon the barrier as she just stood passively in the arena, resulting in me dying. Not a nice way to trash currency used in making a juiced map - anyone else had the same issue?
