Pycnonemosaurus icon bug

When using the head slam attack while holding an item as Pycnonemosaurus, if you drop the item mid-attack, the mouthguard icon stays stuck on screen. The skill may also stop working.

When Pycnonemosaurus has the mouthguard active with sensory, picks up an item, uses head slam and then drops the item, the mouthguard icon remains stuck on screen.

The mouthguard icon should disappear after the effect ends or when the item is dropped, and it should not stay stuck on screen.
