Do you have a previous save with the dwarven council member still around? You can temporarily get someone back with the procedure below, but that may or may not cause a problem during the blessing ceremony.
Harglowe's missing Rimmer post:Alas, I turned the dwarven village inside out, but no Rimmer.
I did solve the problem in the end, by cheating however.
I took an old saved game (a game where I hadn't been to the dwarven village at all) and temporarily copied the data.000 file from that saved game to my newest saved game (after making a backup of the original data.000).
It appears that the data.000 file contains the location of all NPC's and even your own location.
I started up the saved game, went to Rimmers house, talked to him (he was standing in his house, a few feet from the entrance), saved the game and restored the data.000 file.
As per the
Josephine herself stuck in the wall topic, someone had to swap data files to kill Josephine, but recruited the elven council member before restoring their original file. During the blessing ceremony, the screen switched to the Dark Forest when it was his turn to talk, but proceeded fine. Someone tried this for the imp council member (who was missing to start with), but the game would hang trying to change focus to him.
Make a copy of your latest save (or save under a new name) before trying this, just in case.
