Are concrete floors safe to park vehicles on?

[Varpulis 12]

Title.

So far I think I've lost 2 vehicles randomly blowing up after restart because they were parked on concrete floors. Both were facing true north and not on overlapping floors.

 

Anybody else have experience with this?

When a server restarts, the vehicle is re-placed by the server, it is very possible that vehicles will explode when placed on any type of placed floors. The floors also go through the same process too

Use this to protect the vehicles on restart..
