Holding an item (say a torch) in off-hand makes interacting with dank and dock funny :

• when opening a dank in bag mode, the torch in off-hand is be used (e.g. placed in the world),
• one cannot sneak-right-click on a loaded dock to unload it: it does nothing; having both hand empty is required.

These are lesser bugs but they are annoying nonetheless.

First one is fixable, second one isn't

The second one is a vanilla issue, as it can be triggered by holding torches in the offhand while looking at a chest.
