[ARCHIVED] Fire alarm but no fire (invisible fire/Fire inaccessible)

Commenting in case this happens to anyone again. I’ve just worked out a way to stop the random fires that spawn. Make sure your cheats are on “testing cheats true” hold shift and click the fire and select to debug, this will delete that square of fire. You will need to repeat for each square. Once they are all gone you will have your game back to normal.
