Right-clicking Ranger's default bandage causes Result Code 10

[gmjehovich]

This issue is happening on the master branch.

When you right click on the bandage in the Ranger's inventory, you will receive a message "Failed to update inventory [Result Code: 10]"

The bandage stays in place (it doesn't get unequipped and transferred to inventory). Furthermore, if you have any other items unequipped in the Ranger's inventory, then all of those items will be re-equipped.
