This happens if destroy car - set health to 0, set damage zone "Engine" to 0
Immediately and after server restart (if car not deleted by server), the following happens
Engine calls OnEngineStop function every frame in CarScript class for some objects of CarScript class (I seen CivilianSedan and OffroadHatchback)
This happens almost on a vanilla server, only with server-mod that monitor cars...
It starts right after creation ruined car object and then continues up to car deleted
