I started the world on 78.16 and updated to 78.17 before this happened. I will try to reproduce the bug in a creative world and will post steps here if I can.

Apologies, in the future I will post bug reports to the Support section. I am running the current version of TFC (78.17).

While making double copper ingots for my copper anvil I noticed that one of the double ingots in my inventory would should up when I opened my inventory, but would not show up in my inventory when I was at the forge or anvil interfaces. I accidentally placed another double ingot on top of the inventory slot that the disappearing/reappearing double ingot occupied and that ingot was permanently lost. This same issue occurred minutes later when attempting to make my bismuth bronze anvil. After letting all seven of the double ingots cool in my inventory, I then tried to stack them and arrange them in my crafting grid to make an anvil. However, when they were stacked I only ended up with six double ingots. Not a game-breaking bug, but certain annoying.

Success!!!! I updated to the newest version and filled every slot in the firepit with logs just in case and I have charcoal. I don't know which fixed it, but I have charcoal now! Thank you all so much for your help.

Yeah, I just noticed that there was a newer version available when I posted. I have always used logs in the firepit (although I think you only may need one from what I have read), but it doesn't work whether I use one log or multiple logs to fuel the firepit. Also, I always use full log piles in every charcoal pit I construct. Must the firepit keep burning throughout the 18 hour charcoal production period? I thought that it only need one log to get started and then started a timer for 18 hours assuming all other conditions for the charcoal pit were satisfied. Could it be that the full log pile above the firepit doesn't keep it lit for the correct time period as might happen if I were to use a very quickly burning wood type? I will first attempt to update to the latest version and try again. Thank you all for the quick responses. I hope I can get this working.

I am using the latest version of TFC (78.16) and I cannot get charcoal pits to work. I light the firepit and seal up the pit and I see smoke particles coming through the top of the pit as expected. However, when the smoke particles stop many hours later and I open up the pit, I do not find charcoal. Most of the log piles in the pit are untouched and the log pile above the firepit is gone. I have tried about 10 different charcoal pit configurations both with dirt and building a permanent structure with bricks and a door. I have even tried the simplest charcoal pit of a firepit with one log pile above multiple times. I have never gotten any charcoal from any of the pit designs I have tried. Addtionally, I have noticed that the firepit sometimes lights itself on fire automatically. The firepit is cold and no logs in it, but when I try to place a log pile above it the first log falls into the firepit and it will start a fire before I can close the pit. In this situation I did not light the firepit with a firestarter, but it started itself of its own accord. Please help me. I love this mod so far, but this bug is driving me crazy and is incredibly frustrating. Everything else seems to work as it should from the wiki and from Youtube videos except the charcoal pit.
