This bug is pretty simple, but it is quite annoying when prying open copious amounts of oysters. After I pry open two of so oysters the sharpened stick icon goes behind the inventory interface which forces you to drop the sharpened stick before you able pry another one open. When the sharpened stick icon goes behind the inventory, it doesn't allow you to interact with anything in the inventory until you drop the stick and pick it back up again.
