I played a few hours tonight in the latest experimental build [First Person mode] and came across a few instances where loot was repeating itself from just one spot. I successfully looted 5 boxes of .22 round that was just a single box on the ground in a barracks room

I also had this occur at a military jail with food where the food was a single item in the world but could repeatedly loot it; I did not continue to loot to see if it was an endless loop or not.

And lastly, in the barracks I noticed a certain item of clothing would be spawned in atleast 5 times and would begin to spawn inside a large backpack. I highly doubt this was player-placed as it was always the same item and same level of wear on all of the clothing.
