ID Fix

Idfix overrides Id values at the very core of Minecraft objects, in constructors, which, while effective, may have undesired effects: a mod would request to create a block with an Id of, say, 500, and created block would get Id of 4095, because Idfix overrides it to prevent a conflict. Most mods can handle this situation just fine, but some break in most unimaginable ways. Another disadvantage of Idfix is that it overrides the whole configuration system: you have the idfix.txt file with actual block/item Ids, and whatever is written in mod’s configuration becomes almost irrelevant.
