every 8 peices of wood you turn into charcoal you get .30 cents but still its a glitch you should look into it. 8 wood = .4 each and 1 peice of coal is .5 each charcoal sells for .5 each so........ 8 wood is 3.2 a coal is .5 and you get 8 charcoal for 4$ you make .3 each coal/8 logs you burn you need to make charcoal .4625 each for it to be even and to stop this thanks, maskednpc
Lilwilly already found this. Also, there is maintenance and labor involved to constantly fuel the furnaces and what not. So I think it shouldnt be changed.
