Currently testing Terra Incognita with MCW and TC 2.7.2 for Forge 1.7.10. Unfortunately it seems to crash on TC 2.7.2 for Forge 1.7.10 because of an error during ore generation. I've taken a look but have not been able to fix that yet. Terra Incognita does work with MCW though, I'm currently fixing the Tree() and Sapling() resources when used with BO2's and BO3's. Hopefully I can get the BO2's and BO3's working right soon (and hopefully that will also fix some BO2's and BO3's in MCPitman's Biome Bundle) and make a new MCW release.
@NLBlackEagle I can't find the post where you mentioned that your world is available for free for testing purposes but thanks, I appreciate that. First I'm testing some of the freely available biome packs though since I assume that's what most users will download first. I'll be happy to test your world(s) when I'm done with Terra Incognita though.
