I played several different 15-stock Brawls last night all with no problems. Then when I went to play on Mewtwo2000's Facility stage (a Stage Roster Expansion stage), it was fine for a minute or so, then the game froze after a character got on a Warpstar, and no, the warpstar is not the cause of the freeze because it has been used before without freezes; this is the first time.
The characters in my battle were not the causes for the freeze either because I've used all of them before. I don't remember who was in the fight, but I know I was being Zero (Link PSA), Overlord Ganondorf (Ganondorf PSA) was Player 4, and black and red Wolf texture was in the match. I don't remember who the other computer was.
The stage also is not the cause for the freeze because I've played on it several times before and it was fine. So what the hell could have caused this?
which character rode the warp star.
