I appear to have a bug when fighting a computer Kirby at some point during a fight when Kirby starts to use his neutral attack, he then continues to use his neutral attack until cancelled out by an opponent. He doesn't even need to be near the enemy or hitting the enemy, he'll keep going until cancelled by an enemy. I'll provide a video soon enough

Not really a bug. It's just poor AI. If you fight on level 9 CPU this most likely won't happen.

Well, I wouldn't think so for the fact that he keeps using that attack if you don't interrupt him, I think eventually the A.I. would stop.
