Yeah. I just made a 1.5.2 pack today and underground biomes ids conflict with every single mod. Fixed it though, all works so Im happy to know this atleast adds some stuff. Whats MFR though? and is there anything that adds xycraft like blocks? Like the glowy type? I really liked Xycraft to build my thaum/enchanting rooms.
That also said, is there any enchanting mod that works for 1.5.2?
