Jocasta Nu is glitched and needs fixing

Happened a few times were the game lags a lot when Jocasta throws her rifle. But now as soon as she got in her rifle form, she threw her rifle and the game glitches out completely. My SEE disappeared from the battle, characters health went down to zero for no reason but no one died and super laggy gameplay with no animations. And I got 2 losses in a row because of it. This is ruining Grand Arena for me at the moment. Please fix this!
