I have a custom modpack that I've been using for a while now. Yesterday, I updated many of my mods as well as the forge version; from 1370 to 1403. Now, whenever I press play, it takes me back to the launcher after a few seconds. I tested other modpacks and they work. I removed all mods, and it still crashes. I finally found that returning to an older version of forge for the modpack.jar is the only thing that worked. Are the newer forge versions incompatible with technic?
Here is the modpack log: http://pastebin.com/8YeSqKwt
