Yesterday I wanted to cook and I already found a fireplace in a house with fuel in it (wood, rags, and bark), but I was not able to ignite it since it was wet. I tried to take all fuel from it, to make it disappear and make a new fireplace, but no luck. I had to find another furnace in some other house. Today, after about 16 hours, and at least a server restart I passed trought the same house and there it is the same fireplace as I left it, still wet, and not able to be ignited nor make it disapear (see screenshot).
Either it should disappear or be able to make it disappear by taking all the fuel out and then make a new fireplace and place it in the same spot, so it can be ignited.
I have no idea why it was wet. I suppose that someone made a fire outside while raining and then took it inside the furnace. There is no option to take the whole wet fireplace out of the furnace to dry it.
