Not sure if it was intentional to make this, BUT IT IS POSSIBLE TO RING OUT IN BOXSHUV3 i was in a tourny and i kicked my opponents wrist(broke it) and i flew at the wall i raised my arm and my hand went just at the edge of the wall, like right at the bottom portion and i ringed out, i asked (if it wasn't intentional ofc) to please EXTEND the boxshu ring or disable ring outs

It's just a glitch. It's rare, but it may happen if conditions are right. Relax it was just a fluke.

You have to hit right in the corner for it to happen but it is a known glitch , I think the problem was that it was hard to make a box without making a ring and if the ring exists ringouts exist by defualt, it barely ever happens though so its not worth the effort required to fox it
