@hallsigns I've never used the generators but I have this issue with the bug farm, everytime I enter the lot it will say there is a fire, but this is not a visible fire, my sims will put out the invisible fire and my bug boxes will be burned and need replacing. Im assuming its the fire bettles (cant remember the actually name) since the burning seems to spread from their box to the others but like I said there is no flames so I cant really tell
