Alright, so Basically Im mapping an Area for a faction on another server, and Basically the whole time, I see these trash cans over all my hard work, and everywhere littering the Map! (I can only see these when I go into test mode) I cannot edit them or see them when in edit mode, and its really making me angry... I tried spawning one and setting its Cordinated to 0 0 0 But nothing... Can someone and I mean anyone please help!
