When my Server (persistence enabled) crashed, I noticed that on Server restart it can happen, that Items will load up from persistence savegame file duplicated amount of times. Suddenly we hat 3 tents with exast same itemes in it placed, where we had 1 tent before. After another crash those "3x times tents" where now loaded 2 times again = 6 tents with all items duplicated. Seems Server is loading persistance file wrong way. Even normal loot items in houses where now 4-8 times available. See demo video:
