Server 1516 Placed Items are disappearing after being placed for awhile

Game mode: [Online | PVE Conflict official server 1516
Problem: Placed items disappearing.
Region:Crevice in the mountain next to Bjornar’s Stand

I have had now 5 large chests full of items, a compost, a bazier, and an improved stove disappear for now reason. These have all been placed on foundations and a completed base. The Large chests were stacked 3 high. These did not appear in the event log. Decay was not a factor as I log in every day at the base. Being a PVE server I know they were not destroyed by enemy players. The members in the guild have been reliable and I know them well enough to know they were not the ones destroying these items. If anyone knows the cause could you please enlighten me.

  1. Not sure how to reproduce the issue as I am not sure of the cause.
