I collected everything I needed for crafting leather clothing, had my lime, water in barrel, 2 wolf pelts and some nails for later coloring.
However, as I was tanning the hides, the server restarted as scheduled. I logged back on and the barrel is still in "tanning hide" mode, unable to access anything in the barrel, the lid will not open (not even giving a option to) and unable to perform any interactions with the barrel.

Tanning the hide should take 3 minutes if I remember correctly. Been 20 minutes since I logged in back from restart.

Logged out and back in again but no change.
