I was playing on experimental build 5900 today, then updated to 5917, the latest as of this post, and in-game, I changed dynamic NPC spawn from false to true. Saved and quit the game and now I can’t load it due to a game-stopping error about a vehicle fault entry (there’s one about a duplicate bionic ID as well, but that one seems skippable). The only mods I’m using are fairly light and included in the game: simple nutrition and no NPC needs. Chesthole soundpack and RetroDays 20px tileset.
It doesn’t make much sense and I’m not sure how the NPC spawn setting (allegedly not requiring a world reset) had anything to do with it. When I changed it, I did absolutely nothing on that “sitting” besides that. Tried tweaking the world settings to get the spawn option back to false, but it hasn’t helped.

Here’s the savegame in case someone can shed some light on the issue and hopefully restore its functionality:

PS: Well, can’t even create a new character. I get the drive fault error before that screen. Maybe it’s my installation that’s corrupted. Is the CDDA Launcher buggy?
EDIT: No, it’s the world that won’t load. Damn it. Any help would be appreciated.
