ok so I've been trying to complete this dungeon solo on vet for a while and always come a cropper at the final boss, so today I finally figured out how to beat her and promptly went after it. I got her to the second phase of the bats and when I had killed the bats and she re appeared all my abilities stopped working, I could move slowly like I was taking damage slow, Couldn't swap bars, fire a shot or anything. Pretty annoyed is an understatement and I'm pretty sure I made some new swear words up in the process. Wondering if anyone else has had this issue. The lag also was very bad during this time. I will try the dungeon on normal as I don't really fancy trying it again for a while and see if the same issue happens on normal.
