Doryani death glitch

Since for some reason GGG has decided to allow bosses to keep attacking you after they're dead, I just died in Stone Citadel after killing Doryani. When I re-entered the arena, there was no loot, Doryani's giant dead machine was still in the middle of the room, but I had to re-engage with him and fight him again. Once I got him to phase two, he jumped into an invisible machine and just sat there permanently. Couldn't attack him, he couldn't attack, no loot. Just had to leave and be done with it.
