Here’s how it happens:  

First I want to say thanks for this great mod. I have a question. Have there been any recent changes in the loot script? Approximately already one, maybe two days I feel and see changes in the appearance of loot. Previously, when approaching the city, a frieze appeared - it worked the loot script. Now I am in the city and I constantly feel micro friezes and visually see how loot appears and then disappears in a few dozen meters. It's horrible. I apologize for the English - translation google tranlate

sorry for dinging up and old topic, but this map will go perfect with the new DLC that coming

Thank.

Have you tried hosting a different MP mission?  Because I play a gamemode where UAVs will happily fly above 100 meters that's running on a dedicated server.
