I placed a tent on a persistence server and put some stuff in it. I left the server and came back a couple of hours later, after restart! My tent was still there, but my stuff was gone, i couldn't place anything into the tent (but saw the slots when i pressed TAB), can't pack it, can't close the windows or the entrance. There was the option "close window" when i stood in front of a window, but it didn't work.
Edit: It is the "items inside a conatiner invisible bug" 'lagrange' mentioned.
Edit 2: I can't use all the slots !!! I can fill half the tent with stuff, but i can't scroll down to see the other slots!
