Loot not spawning in rad towns and barricades overlapping

Hey, I have had a few different servers from different providers in the past few years and I keep on getting this one problem where once I add Oxide to my server loot won't spawn in Rad Towns and the barricades on the doors will overlap and sometimes take up to 5min to get through? I am almost certain it hasn't got to do with my mods as each server has different mods??? Please help I am unsure why this happens and need to know Thanks in advance and love your work.

 

As far as Barricade stacking you can use this mod: Anti Barricade Stacking | Oxide

The loot issue has to be caused by something else, as Wulf mentioned above

 

Sweet thanks
