Cannot place unit of USAF Aggressor or Insurgent Coalition
I'm currently building a mission that requires USAF Aggressors and Insurgents as Red Coalition. I've assigned my coalitions correctly upon creating the new mission file, and I'm unable to place any object with the coalition of USAF Aggressors. I've also tried placing an object down as another Red coalition, like Russia, and changing the unit's country to USAF Aggressors, but it reverts back to Russia.
When placing a new object down as USAF Aggressors or Insurgents, no object is placed and the object button used on the left deselects as if an object was placed. I've checked the unit list to see if it's getting placed somewhere weird but it's not placed at all.
I'm on DCS Openbeta 2.5.5.36986. JTF-68_Caucasus_Training_v1.0.miz
