Spawned in items are now deleted and replaced after some time - without any player interaction. While I think this is a wanted feature I observed that the recycle timeout is really low.
I saw some items spawn in front of me and after one hour all items were replaced by different items (this was on a low pop server in a remote location so I don't think that somebody picked the items up). I repeated this test on different servers and always observed that items are replaced fast.
I don't know if this is a bug or just a test on experimental but the fast recycle time makes the world too random. You can visit the same area multiple times within one play session and get a complete set of fresh loot every time.
