We've experienced the same thing on a private hive since they applied 1.7.5.1. Also, the tents we pitched before the patch keeps resetting at every server restart to the content it had before the patch. I.e. we now basically have an unlimited supply of blood bags, NVGs, SVDs, 240s, etc etc. Anything we put in the tents now just disappears after restart. Completely ruins the gameplay for us who play with a squad and actually maintain basecamps around the map. We have had to resort to putting stuff in vehicles.
