Just as a further data point, I tested my scenes with a new character.
- Created using LAL
- Ran to mod location without COC
- Entered building
- Not a sausage
I checked the logs and found out that both of my quests were running, but nothing was happening.
Then I saved, quit and reloaded and suddenly my scenes are playing. So it looks like the same pathology as the dialogue bug.
Now it gets interesting. None of my animations were playing at this point. That includes four empty idle markers that I cloned and set to play a random cheer/applause animation, another one that plays indexMemories belly dance animation[1] and two more actors who were scripted to play some idles written specially for the mod.
So I saved that and reloaded again. Now the belly dancer is belly dancing, and one of the four watchers is doing his vanilla applause idle. The rest are just standing there. The other two are doing a stuttering start & stop thing; I want to try a FNIS re-install before I conclude anything from that.
Subsequent reloads had the dancer dancing and nothing else.
Oh, and everybody's hello and idle infos seem to have vanished. [edit] By which I mean still there by not playing...
So: Scenes seem to be affected by the dialogue problem. And so are idle markers, it seems. There also appears to be a non-deterministic component in when deciding what will run and what will not.
[edit]
Regarding "start game enabled", the main quest is triggered when the barmaid's OnLoad event fires, which isn't until you enter the building. Other scenes have their own quests that are triggered by the story manager in response to a keyword event from the main quest. So nothing's ever been started from the beginning for this one.
[1] Just to be clear: Permission to use the animation has been requested, but no response as yet. If I don't have that permission by the time I'm ready to distribute this, I'll simply make other arrangements.
