I was doing 150cc and missed the ramp jump into the cave, so backed it up with a wall jump. When I got into the cave I fell through the floor, I have no idea what happend, anybody know anything about that? Version is JP 1.0 if that helps. I don't have a recording sadly

didnt even play this game ever, but for some reason that sounds familiar to me, i think i saw that happening before to somebody else
you got throught the border betwen the wall and the floor in the edge of the cave trying to backup? the hitbox can be strange idk

Yeah happens all the time. Tunnel floor is all messed up at the entrance

Ok, I wondered if it was some glitchy collision stuff, thank you
