Hello GuineaLynx
I have repaired the save for you, unfortunately I did not have an OBSE file, so display errors can occur, e.g. in containers description .
OBSE cannot be uploaded directly to the forum, so you should put it in an archive and then upload this archive to the forum.
So first of all, save the AutosaveLong1.obse, before it is overwritten!
(you can also give it to me later in the forum, then I'll repair your save with this one, that would be better).
If you run all over Nehrim with Kim in your following, this can damage his controls and thus also a possible quest affiliation.
This also applies after you talk to Calisto and then go through the Lands with Kim again!
(so I would better go alone to be on the safe side).
PS:
-Save very often, also with different fixed game states, so please don't rely save only on autosave or quicksave.
-In case of errors: always load an earlier savegame as a first attempt, alternatively ask us, but don't use the console to fix it yourself,
this can write permanent errors into the game state, which are not always immediately recognisable and may not be able to be repaired later.
