I'm currently building a multiplayer mission and populating the world with a large number of 3CB civilian vehicles with the "simple object" option checked as these are just "atmospheric" props. What I've noticed is if I save and reload the mission file or play the scenario and jump back to Eden the 3CB vehicles seem to have reset their attributes and the simple object option is unchecked.

I've tested this with NATO and RHS vehicles and those work properly, I've gone through the attributes and unchecked options like randomization or anything that I believe could conflict and I've not been able to solve the issue.

So I just wanted to throw this out there, it's not a deal-breaker, the mod is great, I'll just have to use other vehicles to populate the world unless someone else has a workaround.
