There should probably be a rule to not allow Northern Cave Save Glitch to be used. It does not work on Switch either, and I don't know the status on Xbox. This may have been patched on all consoles, but there is a secret hidden reason to ban it. That is for those who have an old version unpatched. They could still potentially do this if they avoid updating the game. You cannot revert back to old version anymore. So I propose to ban save glitch in Northern Cave altogether from being used (in case you care about the merged fair competition). If you don't then it doesn't matter.
