So, found a bug (duh, why else would I post here) but it is a strange one. So while working on building my base I made a calcinatory and decided to cook up some minium dust (which I did successfully). But after I finished cooking it, I used all the fuel, and let it sit there, for like 10 minuets, and it still was in the "burning" mode. Still produced light, still had the little flame on the model and all that, so I clicked on it and opened the gui. Sure enough, there was still "burn-time" after I had used a plank, which is odd, because it was burning through them at an alarming rate. So I assumed Pahimar made it to were when there was nothing to burn it didn't burn, and, I stuck a piece of cobble in there to get the ash. And I received a crash (get the rhyme? :D) instead. No crash report, no nothing. And I can't seem to duplicate it. Sorry about that, but I figured it might be dupped by someone else.

If you crashed, then there is a ForgeModLoader file that has all the info in it related to the crash. Without that, or any other useful information (like mods you have installed and their versions, etc) we cannot do anything to help troubleshoot this.
