NPC mods, what happens when...

    What will happen to my save games when I return to a clean install and then install the NPC mod again?
    I made a savegame at the start of ToB with Amber and Kelsey in the party, but then I decided to start a new SoA game with some other mods. For the new game I returned my game to a clean install and installed the mods I wanted to try plus the Amber and Kelsey NPC mods. Now I'm wondering is that ToB savegame ruined even though I reinstalled the NPCs or can I play it without problems?

    AFAIK you'll have to install the same mods and in the same order if you have to be sure if your savegames shall work.

    Yep - the quick story, simplified (this is a metaphor, not a real detailing - for the real heavy stuff hit up G3 and PPG tutorials on string references and the WeiDU documentation):

    Each mod adds extra entries to the main index. Basically, new books tucked up on the shelf. Except that when you add books, they add on index numbers.

    WeiDU works by allowing you to take all the books off the shelf, move them into new orders, etc., etc. - basically it allows you to shuffle books around without having to destroy the library and rebuild. This is no problem if you are browsing a new library, as the index is recreated and relinked in each new game. But when you are restocking the shelves, it gets tricky.

    What WeiDU can't (doesn't) do is set up empty shelves and pre-label them. So when you add Mod A, Mod B, and Mod C, your library looks like ABC indexed 1,2,3. When you uninstall B, it looks like AC indexed 1,2. If you add soem new mods on, ACDE, you get 1,2,3,4.

    The savegame expects index 1,2,3 = A,B,C. You have reinstalled in a different order/new mod stuff, so the index now points to 1,2,3,4,5 = A,C,D,E,F. "Scrambled strrefs".

    Adding a mod on the end isn't too bad - it adds to the index, and things are fine. And if you put everything back in the same order, then you are probably safe. But moving, removing, or placing mods that add dialogue and usng old savegames is pretty tricky - you have to expect that somewhere, something is mis-indexed.
