I have been having the issue with the login to my server where it says
"Forge Mod Loader has found ID mismatches
Complete details are in log file
ID 102 is mismatched between world and game
ID 335 is mismatched between world and game
ID 79 is mismatched between world and game"
This issue has been brought up in this forum "http://www.minecraftforum.net/topic/1916001-forge-mod-loader-has-found-id-mismatches/" and supposedly has been fixed from using Toomanymods but how do you install it for Tekkit?? There are no videos on Youtube about it so I thought I would come here.
Thanks!
