Recently I've been getting back into FTB, but whenever I start playing I suddenly crash and I get the error log of "Failed to write core dump". I have looked around but haven't seen any fixes to my problem. So far I've reinstalled my graphics drivers to their updated version, downgraded my graphics drivers, and reinstalled java to the latest version. Yet I still haven't fixed my crashes, if anyone could help me out that would be sublime. Thank you.
