I've been working on a modpack that I plan on releasing for 3rd party use on the FTB launcher. Pack thread with pics here. For the map, I was planning on using Tinkers' Construct Blue Slime dirt and Slimy Grass. Unfortunately, Vanilla Minecraft's Superflat preset generator doesn't seem to accept modded item names, so I've been forced to use numerical item ids which change quite often and break the map. Every time the map breaks it takes me about 45 minutes to rebuild and a mandatory world reset for anyone playing it, which makes it unusable.
I need one of two things:
1. A mod that alters the Superflat Preset generator to use modded Item names.
2. A mod that adds a world type that basically creates the world I constructed for the modpack... plus different colored slimes that only drop vanilla slimeballs.
