So the bug here is that these golden chests I cannot interact with. It seems that there's a force field around it (I'm assuming it's set as a solid object so you can't pass through, but the boundaries make it so you can't get closer than where I am positioned.
It seems every dungeon has this issue with the golden chests, so I can't use dungeon keys on them.
Last comment people mentioned issues may be tied to having multiple save files, but this one I wiped everything for 4.5a, and have no other save files.
