I don't get it. What do we need block IDs for in 1.7.10? Haven't they been replaced with forge?
That's just with assigning the block IDs (and assigning them by name). The hard ID limit was still there, as I discovered when trying to run Gregtech, Plant Mega Pack, Lord of the Rings, plus my usual mods list. Previously, my only option was to disable blocks or remove one of the mods to free up block IDs. This fixes that issue - in much the same way as other mods fix the issue with potion ID limits.
