That one annoyed me, but at least you can wait for 3 game days in an unpopulated cell and it'll force the resets. Should not have to at this point but it seems like they would have to append the day to the end of the savegame format and potentially risk breaking pre-patch saves. They're probably having trouble altering the formatting and variable cotent of the saves since currently the bug is a result of there not being a varible in the save structure for day of the week! You'd think they could probably write a script that correct by using the date since the numerical date value is at least save correctly.
Though a complicated post (To me at least, hey's its 1:30am here), this does bring up a point.
Some bugs may not appear to be immediately fixed, so it may be worth finding an interior cells with no NPCs and waiting three days for the cell resets and see if that clears the issue. May not always work, but always worth a go.
