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?
