Map question

I’ve got a map I made just for fun which is an enclosed track using baller spawners, movement modulators set to speed boost mode, glass walls and glass floors.

The problem I’m having is an occasional baller will be outside of the track as though it went through one of the glass walls or floors.

Any idea what the issue could be and a solution to the issue?

EDIT:

I see where an occasional baller is falling out and it acts like the glass isn’t even there even though it is there.

EDIT:

Also there will occasionally be a random glass wall or glass floor missing in a random spot, but is not causing this issue.
