Hi @TastierOsprey80
This sounds like a collision issue. I’ve seen it happen with my scenery too when I place something like a custom collidable luggage container in a place where the ground vehicles want to be (we can’t move the ground vehicles either).
Best to let the developer know so they can re-position things and release an update.
There are other things you can do like remove the ground vehicles, but it gets very messy.
All the best.
