We've got no current bugs which need tracking down, thanks. The TODO file has a few things, but they're mostly just missing features and gameplay adjustments.
Of course, since it's open source, if you really want to see how it works you could even recompile from source (as long as you can find a version of Unity old enough). The code base is somewhat organised, but has had to compromise in a few areas. Certainly not my best code, but sadly not my worst.
Thanks again for the help, though. Glad to have save/loading actually stable and functional for all known configurations. One problem taken care of for the immediate future, leaving more time to implement vampires and zombies.
