So, I don't know how these questions work exactly on the forums, but, I've downloaded this modpack: https://www.technicpack.net/modpack/magitekk-magic-and-tech.988932
And for a day, it worked fine, but now, the game launches correctly, but anytime I try to load my world, it just closes. No bug report. No crash report. Just closes the game and pops the launcher back up. Anyone have any way to help?
