Vehicle Pawn Freezing when not being looked at

Hello all, I am experiencing a weird issue. I’m using the Chaos vehicles from the vehicle example in UE5.1 I have set up a small experimental project where the vehicles are possessed on spawn. (I’ve tried creating an AIController and just letting the project do it automatically)

lets say I set 4 vehicles to follow the path laid out infront of them they all work fine. only until i break a decent line of sight from them. Then it seems only the one infront the first one spawned still moves but the other 3 just seem to completely die?

they start moving again when looked at like they had just gone to sleep or something while not looking at them. I don’t understand because as I say it seems the first one that is spawned seems to just follow the path with no problems. I’ve tried even setting the always tick pose just in case it was possibly related to that.

Thanks in advance.

I did find that if i set the bounds scale of the skeletal mesh to 2000 it would keep working. so clearly its an issue with being unrendered or something. I don’t know if there is another solution to this. But thats all I have found to work for me at this moment in time.
