Twice now I've fought adv Spite at Insula Primalis with the team of Legacy, Fanatic, Wraith and Ra. Twice now after Spite has flipped he continues to plink the heroes for 2 damage each until they're all dead except Legacy. Legacy has fortitude out reducing damage by 1. The message Spite would play a card but deals damage instead pops up, everyone takes damage, repeat. This goes on until everyone but Legacy is dead and he has 1 hp. Then the message repeats over and over with no damage being done. The last time I put my iPad down and walked away. Ten minutes later Legacy has 1 hp and the message is still repeating.
edit: and I just found this...
