no idea what caused that
just popped up in the middle of my game
as for the donut thing:
I was playing as buu, I candy beamed someone as he was swooping into me and the candy menu popped up. He began to prepunch me as i turned him into a donut. The donut appeared but I was still being hit by something. After that he input his directional arrows with no player model. after the stuggle ended he still had no player model. He charged a kamehameha and I could see his kamehameha sprite floating around but not him. I dont know if if he could cause any damage since he should have been dead... I mouthblasted him and upon his respawn he everything was back to normal.
