hopefully, the images would explain it, but if not then I'll explain it myself. It seems like every time on my server I open a cloud chest or static one at that, the inventory of the player opening the chest is removed and hidden, and if going in creative after opening the chest before the inventory updates itself, the items are deleted.

The issue is that not only are my items being hidden but have a high chance of being deleted if I were testing something. Even more so, the inventory of the Cloud Chest doesn't even show for no reason I can find, as it seems it can't be any of my config or conflicting mods as it works perfectly fine in my single-player worlds with the same features of the server. I've checked everything I could to see if there was a conflicting config or mod, but to no avail
