it's always nice to see the mod developers be faster then us
ID conflicts is still the easy part of making a modpack, getting everything balanced and ironing out all the incompatibilities is the big pain in the arse
I find seeking out all of the item ID conflicts is the real pain. It takes a while to find them all and then the rest of the afternoon sorting them. Then the balancing is just annoying but I enjoy it more as it excites me for the actually playing the game, and it's not all numbers.
