I got to the prisoner in the fire dungeon and on the second line of his dialogue, my computer froze and restarted in quick succession. When I went to load my save, the continue option was greyed out. I saved right before entering that room. Uploading my save to a save editor shows there's still data in there and it at least looks like my inventory is intact. I've tried editing a file to resemble my first one, but any editing created a copy of Lace that halted game progression.

Here is my save file.
