Hey, just an FYI that the post-fix version should address this issue by and large. If you end your current game and reload on the new version you should have a much better experience with the sanity check (it should only be failing about 3% of the time but it was failing a LOT more than that, I know.) An embarrassing error on my part. (For reasons involving me using default MZX savefiles, you'll want to die in your current run.)
