After problems with the game after the update where the fireplaces didn't have a slot to put fuel in I uninstalled everything and deleted the gamefolder to be sure everything except my saved files was gone.
Reinstalled the game without the DLC (styx map) and the old problem was gone. Gone also were several of my skills and talents... My character is lvl 21 and all my skills in building shelters are gone. I can't even build a thatch shelter. Before I could make stone houses. I still have almost all old skills up to tier 3 so why just these is gone is beyond me... Any ideas?
