Hello, I've recently made a modpack and it's all working fine, but then if I am to close the game and go back to the launcher I have to reset the pack or re-add the pack in order to play again. If I do click play without resetting the pack it starts and goes back to the launcher.
Here is the crash report: http://pastebin.com/086QbMTq
And here is a link to the pack: http://www.technicpack.net/modpack/details/mindstorm-modded-survival.290890
(Also I'm sorry I'm not exactly sure where this should be posted, but if you can help me out it would be appreciated)
