i have that one and it works just fine, not sure whats wrong or how it was fixed tbh
So just to be clear, now your ammo crates such as:
UNBasicAmmunitionBox_EP1
USBasicAmmunitionBox_EP1
USOrdnanceBox_EP1
USVehicleBox_EP1
Work fine now on your DayZ.ST map?
Can you post a couple database entries for boxes you've verified working to help us out? Thanks!
