Multiple times people on my server have noticed random items disappearing from their warehouses. Recently I took 51 iron ore from my warehouse, pulverized it into dust then smelted it all into ingots that went back into my warehouse. Coming back later I found the ingots gone and the 51 iron ore instead. This leads me to think that the items aren't necessarily disappearing but the entire warehouse is being rolled back in time? These rollbacks or item disappearances don't have any patterns I have noticed so far for when they happen.

I have the same problem on the server I am on. Have built a 16 border upgraded warehouse with small and medium storage in it. First time I placed some rotten flesh in. Logged off and came back an hour later to notice it was gone from the warehouse. Second time I placed various stone blocks inside. Logged for around an hour came back to them gone again. Third time I placed 2 items inside. Logged off for the night, around 13 hours. Came back to them still inside. Seems random when it deletes them.

I am no longer running the server which I had this problem but I suspect the issue might have been related to the server running out of RAM.

You mentioned it not disappearing overnight which is when the server would be using the least RAM since less/no people would be on right? My server was running on less RAM then it probably needed and would tend to hit the limit with multiple people on.

Is your server maxing out its RAM capacity? If so that might be the problem.

I can't confirm any of that as the server I play on is in Sweden and I am Canadian, but your logic does make sense.

Without the ability to replicate this issue, it will be hard to fix it. I haven't noticed such issues when I was testing other warehouse related things. I will leave this open for you and others to add information if/when you get it, but there isn't really much more we can do.

Witam. Mam ten sam problem, itemki znikają z magazynu. Najpierw znikło mi 9 enderpereł a następnie zauważyłem brak kilku bloków diamentowych. Są to cenne sórowce więc ich brak zauważyłem, innych itemkow ciężko pilnować
