I recently had a nasty raid use flamethrowers against a wooden wall for a while and had trouble cleaning up the puddles of prometheum left behind. Now the logs are filled with exceptions looping : "Exception ticking FilthPrometheum1171753 (at (161, 0, 145)): System.NullReferenceException: Object reference not set to an instance of an object"
It causes a lot of lag as this bug messes with the ticking of the firestarting.
Is there a way to fix this bug ? I would like to keep that savefile.
