Attempting to drive an MTS/IV Vehicle as a possessed entity causes player to disappear

I don't know how to explain this, but basically in order to replicate this, you take Immersive Vehicles and any vehicle pack, kill yourself and possess a zombie/skeleton (and wear a cap for convenience), then hop into any car.
Simply being near any car from Minecraft Transport Simulator (AKA Immersive Vehicles) causes player physics to freak out, causing anything from the player being flung between two coordinates above Y level 300 while being unable to die, to straight up ceasing existence.

This is a bit of a problem for gameplay, because it does pretty much break the world for the player (assuming they don't know how to reset their playerdata) and you can't race in a hotrod as a zombie.

Does this happen always for you, only when you exit, or only when you are near it?

Pardon the slight delay.
Always...
