I started playing modded MC a while back, everything works fine except on twitch launcher, A few modpacks work great, (Mage Quest, Lite 3, Dude where's my blocks?) But some like Stoneblock 1 and 2, don't work, I've tried manually downloading Stoneblock 1 and installing it on the twitch launcher, same problem.
