Known problems:
- On some computers, one of the mods (believed to be Ars Magica currently) conflicts with the OptiFine Preloaded Chunks setting. Turn this setting Off and you shouldn't crash anymore.
If you REALLY need help for some reason, message me on Discord at Poseidon#1337 and I'll help how I can when I'm not busy. This is my first mod pack so I'm not fully aware of everything I need to do.
