Ok i was doing so research and had just compleated Thumic blood, as soon as i clicked the scroll my client crashed. i relogged and now every time i try to run the pack it just closes my client. Linked is the crash-report
Code: Caused by: java.lang.NoClassDefFoundError: scala/actors/threadpool/Arrays >_> somehow, the scala library (used by vanilla minecraft) got messed up, or deleted... You will have to wipe the entire directory where your launcher saves your modpack instances, and re-download the packs that you play. Likely, you wont be able to play any other modpack at all, as the library files are only downloaded once and shared between the packs
Ok so I deleted the MYM so there was no instances, reload Thaumic Skies, and got the same problem, so I took it 1 step further and formatted my PC (been meaning to do it for while) and have done a fresh install, im still getting the same problem. I have also tried Hypovolemia, this works fine. Latest crash-report linked
Issue is being caused by EnderIOAddons, was a bug in that mod, which has been fixed in a newer version of the mod. @MaelstromPhoenix needs to push an update to the pack containing the new version. Quote from the changelog of enderioaddons
