Oh well, I say as I reboot my computer, I'll just play around with the Ridley model for a bit. And so I did.
Once I was done I decided to open up LA again to do more quadrant work
Oh, damn, the save file must have been corrupted when Max froze, good thing I've got autobackup turned on...
Oh... messing around with Ridley... overwrote... the LA backups...
...
...
So yeah, I have no working back ups of the Overworld that aren't nearly a month old. Thank you, Max, for not making separate autobacks for separate files.
I am at a loss as to what to do.
