I've recently got a problem with this modpack. At the start i downloaded 1.1 version and everything was working perfectly. Then the update has been released. Of course i wanted to update modpack, but minecraft refused to load version 1.2. It said 'Failed to load mod' and nothing more. Like, name of the mod or else. I've already tried to create a new instance in MultiMC, install the modpack on fresh new minecraft, but nothing helps.
