Player falls through map when he dies

I’m working on a zombie survival game and ran into a problem.
Every time the player dies it glitches through the floor.
does anyone know how this happens and is there a way to fix this?

this is the game link so you can see what I’m talking about:

never mind, it actually was a problem that’s only in Roblox Studio, in the game itself it works just fine.

That’s a weird bug for it to only occur in studio, make sure you don’t have any malicious plugins installed.
