I never heard of that plugin before but I was looking at short clips of it. The player is the one who places it down, so I guess it matters on the User if they can properly place it down. Just incase make sure to turn off CanCollide and if the problem still happens then I don’t know.
Alright I can see it now. This is a guess but, in his thread he said that he fixed the overlapping problem. So if you can reverse that then it should be working. It was originally like the one in the GIF, but afterwards when he fixed it, overlapping couldn’t be done anymore and showed a red box.
