PlayerModel issue

On my TTT server, I have a player model, that, on some maps, will randomly teleport the player to an area where a teleporter outputs players(Ex. TTT_67thWay.) Does anyone know what causes this issue and how to fix it? I posted this in developers mostly because it doesn’t involve the actual playing of Garry’s Mod.

Does it only happen in certain spots when facing certain direction? Which model is it? and it usually only happens on spawn when it auto equips from the pointshop.
