Not entirely sure if it's a problem with heroic or the game itself, since the game didn't launch, but heroic didn't show any errors either, but just in case, here is a log for heroic. https://paste.debian.net/1301792 here's the log that I got when pressing "Report a problem running this game" https://paste.debian.net/1301793 Could it be because melvor idle is supposedly native? Although I'm not to sure about that.
