When you blow up the Moon Stone with Gunpowder or Slurtle Slime while the Moon Caller's Staff is on the Moon Stone. The staff pops off while the light is still there, even when you restart your game.
Steps to Reproduce
what i was doing was that i just put gunpowder next to the moon stone with the moon caller's staff on it. Then when the gunpowder blew up the light was still there, even when i restarted my game. The only way to get rid of it is to repair the Moon Stone and put the staff back on it then take it off.
