@SavageCDN No gameplay changing mods exept C2 - Command and Control. I'll try without this one later today... Otherwise it's just CBA, Alive, CUP and a few maps.
When I remove the OPFOR units, civilians behave properly (walking around, sitting...). I thought about the faction relations, but everything is on low.

EDIT: C2 is not the culprit here. No changes...
