Forge Bug fixed, it was completely my fault. The only way to fix this is to reinstall the pack or wait for the next release if you don't really care :D
Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Type in the modpack name (GameCraft-Pack) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select GameCraft-Pack from the list on the left. The launcher will handle everything else!
