Error message reads: "Forge Mod Loader has found ID mismatches. ID ___ from Mod Natura is missing. (Missing ID numbers are: 12662, 3284, 12663, 3285, 3286, 12660, 3287, 3280, 12658, 3281, 12659, 3282, 3283, 12657, 12670, 3292, 12671, 3293, 12668, 3294, 12669). Do you wish to continue loading?" I've tried reloading the mod pack to no avail. I tried replacing the mod JAR file to no avail. I am not a computer person by any stretch; I just like playing Hexxit and I miss my Natura stuff. Pls help?
