I seem to have a similar problem. I'm stuck at the 2nd fight, and it seems to be rather ineffective when fighting the boss, so I keep on losing. I would change my pokemon but there isn't a PC. I don't have anything to change the field effects and even if I do beat the boss, I might end up getting stuck in the wall because it keeps glitching. I do hope that this can be fixed. I don't really know what I can do about it. :(
