Can confirm that the loot seem to "double" on private servers in a strange way sometimes. One building has for example 1 rice and one powdered milk. Same building butanother room had the exact same. Over to the next building there was 1 red hat and a kitchen knife. Another room again the same. Seem very wired.

Devs, please help us :S

Because we get no help, we reinstall the Server now

Now the Server starts always on 4:27 and in the Settings the time is set by 10:30.

I recently raided Zeleno and met somebody friendly who explained the new loot respawn system. We kept emptying out the barracks and new loot spawned, and it would always exhibit this type of behaviour.
Spawn 5x Aviator sunglasses -> clear them out, throw them outside
Spawn 4x SVD Mag -> clear them out, throw them outside
Spawn 5x UMP Mag -> clear them out, throw them outside
Spawn 6x Binoculars -> clear them out, throw them outside
Spawn 4x Gorka pants -> clear them out, throw them outside
Spawn 3x Smersh backpack -> clear them out, throw them outside
Spawn 1x AKM etc. etc. etc.

Lets hope the next update will fix the loot issues.
