I do still have a save game with the bugged quest available, but I can’t say for sure that it wasn’t caused by mods. Even if it was caused by a mod, the name might stay when I disable them. Like, if I used a mod that changed map generation and then disabled it, the map wouldn’t change back to normal generation, and this might be a similar situation. I also can’t recreate it without waiting forever for a new broken quest to generate, since most of them work fine.
