This exact question has been asked before and I have almost the exact same setup as the original OP. Miyoo Flip with GammaOS running v2.0. I'm on my way to Rayquaza and one of the grunts always uses an Aipom who always goes first using double iron bash and the game always crashes. Any way to fix this? Do I just pray for RNG, or do I need to repatch my rom with an older version?
