I created a heli pad in rust edit. When I place the mini, it doesn't appear in game. The same happens if I try to place one on top of Oxum's gas station. What's going on with this and is there a way to make them spawn in these places?

Not in RustEdit, but the Monument Addons plugin supports placing vehicle spawn points.

I think the issue is it can only be spawned on the ground and not on a prefab. I thought using an invisible blocker would work, but that didn't either. Still not sure how to sort it out, but thanks for the reply.
