So, I have been using this assortment of mods for quite some time (manual list, thank you), and just recently added some mods. All of a sudden, my modpack won't load. I've tried running without any mods, and it did work (though the game did crash within a minute on the title screen). I notice that the game crashes within the second phase of mod loading.
Everything you need should be locatable in theCrash Repoand Log file, but reply if you need more!
