Oooh! I can help with that in the future!

That thing does conflict resolution the RIGHT way. None of that buggy auto-assign junk that never assigns blocks correctly and can't handle added/removed blocks via mod updates or removals.
Handles Biomes, Entities, Potions, and Enchantments, and soon dimensions.

I can confirm that the patcher will work, though Binnie did a few derptastic things that might cause you issues with Reikas mods. Well... he's just exposing an issue that would cause you problems later, but that doesn't help NOW
I was the lead pack designer on Reika's Dev server, and we updated to Binnie's... ye gods was that a production, though that might have been the server-specific tweak mod.
Edit: Was is the operative word. I'm not playing on the server anymore. Still semi-active in that community, just couldn't handle the rock-and-hard-place situation I got myself into, nor did I much like the pack that ended up growing out of what I originally developed.
