Hello all, I am having the same problem as OP where some friends cannot see the vehicle I have spawned (I am just floating in the air to them) but SOME friends can see it. Cannot figure out what determines the visibility.
Anyway I see that a solution has been found. My question is: where do I drop in the code? The way I play with my friends is I host a join and they find it in server browser under 'Internet', so I don't believe I am using a server config that I can edit and drop the code in, but I may be wrong..
