I currently cant craft a wood roof. I've relogged miltiple times, exited Steam, restarted PC, emptied inventory, reharvested mats, & nada. When I have the mats its not grayed out & says i can make 2, 3, etc. depending on the mats i have. I can make other recipes, just not that one. Guess I'll try dying & then zoning if that doesnt work. I havent respecd or leveled recently either.
