I searched around a little but didn't find anything helpful... Does anyone know what the story is with the final 1.4.7 recommended release of ultimate? Near as I can tell, 1.0.1 is still the recommended version. I've tried the other four versions in the launcher, and when I try to open a SP world that was created with 1.0.1 with any of them, I get a bunch of mismatch warnings, mostly surrounding GregTech. Does anyone know what these errors pertain to?
