New added Containers for CH-67 Huron (Fuel, Cargo, Ammo, Medical and Repair) has the same problem. AI pick them up fine, but Waypoint Drop Cargo does not work.
AI get stuck never drops the cargo and never completes waypoint.

Same problem here!

Stumbled across this: http://feedback.arma3.com/view.php?id=11834

It seems that if the first unit i place on the map is one of the new APCs and afterwords infantry etc, the dedicated server will get stuck with the CfgSkeletons error.

If the first unit is infantry, and then one of the new APCs the problem is gone.

Don´t know if the problem/issue is the same on local machine.
