Well, it apparently worked, but as i expected, everything already in my world that had it's ID changed simply vanished. Meaning i lost all of my spell recipes, all of my everything that had to do with Ars Magica.
But the real downer came when i re-created the world, and it wouldn't generate the massive block of ice feature next to the RP2 volcano at spawn, with the chests containing lots of spell recipes and Ars Magica items. Damn it. It was such an awesome seed because of that + the village nearby, and now only the village generated, and the thaumcraft barrow that was close by did not generate as well. Really disappointed
I'm just going to cheat a base & farm like i had in my previous world in another seed and continue from there.
