I've got a bug where once I knap a single item my knapping interface does not reset. I close it and right click with my stack of rocks again, but it just consumes a stone and open an interface with no stone in it, as if I'd already knapped the whole thing away. I can close and relaunch minecraft to fix it... once. Then I have to do it again. It's "shaping" up to be a very very long stone age. Pun somewhat intended.
Are animals meant to be nearly impossible to find? I read on the TFC forums that there'd been some biome-limiting done, so I started a creative world and flew around for a long while, all different biomes. Tally: 13 pigs, 4 wolves, 2 deer-things. Not a single sheep, cow, or chicken.
This mod is simply splendid! It adds so many things that I wish had been implemented earlier. I'll admit it was a tad confusing at first and I had no idea what knapping was or how to craft stuff. I had to visit the TFC Wiki a few times and eventually got it. I noticed that a few pages were missing and wondered if you needed help filling them in, because I would be happy to support this mod. I might even texture some things for you if you need them textured.
