again, i am aware this isn't usually the place for this, so i appologize if i cause any nucence. i am playing with a very slightly modified version of the Agrarian skies mod/map pack from the FTB launcher, i've added, open perhiperals and open perhiperals addons, nothing else. thanks for any assistance!

You may need to fix your config files to resolve item ID conflicts. Remove any additional mods you've included, then use NEI to generate an item ID list. Check through the config files for your additional mods and resolve any conflicts.

If you're unsure how to fix your config files yourself you can use this http://www.minecraftforum.net/topic/1928632-164smpforge-idfix-and-idfix-minus-mods-for-resolving-id-conflicts/ as it's great to have if you have alot of mods installed

I'll second TheOddByte's recommendation. For making your own mod pack it sure beats trying to sus out multiple ID conflicts - just drop the mod he linked into your mods directory and run MC once. You can remove it afterward if you don't want the extra mod running.
