Can you upload your save somewhere so I can take a look at it? I may end up needing to do a more comprehensive overhaul of the saving/loading process.
It looks like there are a few issues here, I have a fix that should allow the save to load with some error messages rather than just blanking out. Some equipped items may disappear but the game should be fine after that. I should be able to get a build up later, I'm working on including some other fixes to hopefully prevent the issue from reoccurring.
