No I don't. I am playing from an earlier save now and the bug did not occur again.
I am concerned about something else : the "cemetery rumours" quest does not resolve itself after feeding the vampires and having sex with them. I know that it apparently takes some time but since last time it did not event after reclaiming the castle I am concerned that it could cause other issues of the same kind as my carriage problem from before.
In case it could mess things up I'm waiting for the quest to complete itself before visiting victoria and causing the death of the mayor. Is it necessary or can I just let him die ?
