Unable to move items out of backpack or chests

(Pre-existing dedicated hosted by Nodecraft) I am unable to move items out of backpacks nor any external storage (chests, etc.). After selecting the item doesn't show the item being removed from it's prior slot and after 1-3 seconds the item disappears in my cursor. I am, however, able to eat items from these slots.

No logs/errors are printed to the server console when performing these interactions.
