yep, i edited the code to run 11 versions at once and now i see it is getting stuck, must have just been getting lucky before because it definitely didn't get stuck in like 30+ runs...
i did some more testing and it doesn't appear to be anything to do with the raycast, if you do a check a variable if the ray is false it still remains at the original value so it looks more like the box is just getting stuck on the corner of the ground or something rather than the velo not being applied.. this is especially noticeable as when you first run the app the player blocks appear to have a gap below them but as time goes on they get lower and lower

with that in mind i found if you push back up against gravity it doesn't get stuck - i left this running for a good 10mins and not 1 got stuck
