the community is very grateful for this fix, this will be a game changer, but none of the complainers will come to say this now that the long time ADS bug is fixed.

It is possible that the vehicle hitbox was touching the tent hitbox when 'live' on game. Once the server restarted and the engine respawned the vechile it was sent in the air due to the collision of those hitboxes.

My guess is this is some conflict or related with the mod that obfuscate the edges of the screen. Also looks to me this is not an official map and/or modded stuff.
