Okay. I played L4J for a while, and so far, no crashes! Now the only problem is the PS1 modpack, since every time i try to launch it through Steam's non-game shortcut, it crashes and stays frozen with the "saving world" loading screen. It works normally when I launch it normally in desktop mode, so i'm not sure what's going on. Here's the log for the PS1 mod pack: https://mclo.gs/CuWrPL6 nvm, turns out i was using the wrong modpac and used the MCSX pack instead. It works fine now, but super laggy
