IC2 thinks I am using a mod pack?

  • Not sure why but I updated all of my mods today and one of those achievements popped up and it NEVER goes away! I assume it to keep mods packs from having IC2 but I installed these mods my self how can I fix this?




    I am using MutiMC and these are my mods:


    Forge V4.3.5.318


    Railcraft V6.5.0.0


    Thermal Epansion V1.0.7


    Buildcraft V3.2.0 pre9


    Code Chicken Core V0.6.5


    Not Enough Items V1.4.0.5


    Ender Storage V1.2.0.1


    Mystcraft V9.3.00


    Industrial Craft 2 V1.107.46


    Iron Chests V4.0.3


    Forestry V1.5.0.2




    Did I somehow magically have the same mods as another mod pack?
