I’m not sure what the deal was exactly but I was playing with Shayne and Aurox (first time). Things were going well until I reached the giant drill room where you have to fight the ice golems/creatures. The boss one was immune half the time to my attacks and his minions would become immune suddenly sometimes.
Then the ice golems in the next room were immune forever! Took me a long time to kill them. I almost gave up and just ran through.
Finally reaching ISAC, I was glad the fight was almost over because it was taking entirely too long. Then ISAC was immune and that fight lasted way too long! On top of it, ISAC tried to jump on me and twice landed outside of the wall where I could not get to him.
Over all I was in that one match for 40 minutes! IT seemed like it was mostly my throw that they were immune to, but boy was that annoying. I don’t know if it helps, but here is the match ID it gave me at the end of the battle:
