I’ve been testing a script I created for persistent cars using server side CreateVehicle, the vehicles created with my script remained on the server for at least 2 days (I never restarted my server during this period), even with no players connected.
When loading in and teleporting to the place the vehicles are at, it may take a few seconds (while the models load) for the vehicles to reappear but they all remained in their original locations.
I used artifacts 2997, with +set onesync legacy
for testing this. Have not tested on Infinity.
Based my script off the repro used in this thread.
