If the game loads an armoured vehicle such as the Marshall, Panther, Marid or Kamysh, before a 'man' class unit, the game will fail to load the OFP2_ManSkeleton model.cfg, which causes all Man class units to break, and displays an error.
In order to accomplish this, the game must be started with the -world=empty parameter in the "Launch Options"/"Target" line, then if a player loads Stratis in the Editor and places down an armoured vehicle (e.g the AM-7 Marshall) with the player set as a crew member (e.g. Commander, Gunner, Driver), then hit 'preview' to start the mission.
My experience is that the game will take a long time trying to load the mission and cause the HDD to make a lot of noise, before it reverts back to the editor screen displaying the error message: "No entry 'config.bin,CfgSkeletons'." If you then click 'preview' again, the mission will load, but the skeletons/animations of all Man class units in the mission will be corrupted.
All Man class units will remain corrupted until the game is restarted in a way that does not trigger the bug.
If the player loads the mission as a unit other than an armoured vehicle, but with non-player armoured vehicles in the mission, this bug will not occur and the mission and Man class units will load as normal.
If the player loads the game without the -world=empty parameter, this bug will also not happen because the "menu screen mission" for Stratis will cause the game to initialise a Man class unit before and Armoured vehicle. {F21011}
