Re: why are there ???? marks for all the characters i have

Well, as long as you and your son is able to access every character variant in the game - it's just a small, minor glitch that won't be of nuisance at all when you enter a match. I'd say, personally, just ignore this glitch entirely because there seems to be no easy solution to this little problem.

My last 'possible' solution to this would be to try and unlock every variant in the game and see if that fixes the glitch. My hunch is that the game knows that you still have variants missing, but doesn't know which character variants are missing, so places a ???? on each character class list just to be sure.
