It was in only one specific scenario, if I jumped onto a floating platform on the edge of where a slope was, once or twice it fell straight through the platform. I'm guessing the slope and the straight side of the platform are separate objects and there's a bit of a gap in the collisions?
Were the things you were trying to jump on sand tiles? If so that’s intentional, if not I’m not sure but yeah, it might be due to the different colliders
