Gamebreaking Neeko bug

So, today i have encountered a bug while playing Neeko. As you can see in the video, if disguised Neeko gets polymorphed just as she casts her W, she breaks, her stats break so she can't use spells(has 0 mana)(but her w works), can't use auto attacks. Summoner spells and items work normally. The only way to fix this is by disguising yourself as another champion several times until you get your normal stats back. Considering her passive has 20s cooldown, this can be gamebreaking in teamfights, so please fix this soon. I know this is very unlikely to happen in game, but it happened to me, and it will probably happen to other players as well.
