Hmmm, if Claudius is dead then that does sound like a bug, unless there's some bit of plot that I've forgotten (in which case it's at the very least unclearly signalled, but honestly it's more likely a bug.) I'll check it out. Thank you for the report, and sorry for the anticlimax—please accept my apologies and my official recognition of your status of Official Winner and Certified Tragic Hero!

I tried again from an earlier save, and this time achieved 100%. I don't know that I did anything differently except last time I saved immediately after killing Claudius while this time I saved before entering the castle for the last time and completed it from there without furhter saves. Don't know if that has any bearing on the issue.
