I'm having an issue in game. I joined a realism unit, so I have ACE/ACRE installed. For some reason, any guy with an RCO sight does not have mil dots when I zoom in. I've checked the ace keys and made sure to press shift L to try and turn it on, no luck. I also completely removed all the mods, deleted the game, and reinstalled it. Still have the same issue... No clue why. Anyone have any suggestions I could try?
