Basically, I have the same problem again. I know I can get around it by making it start when the quest starts, but having just dragged myself beaten and bloody from the wreckage of a 50 phase scene, I think I'd prefer to have lots of small scenes stitched together for the next one. Having a quest for each of them seems wasteful.
The really odd thing is that this is happening in stage 30 - two stages have happened by this point, including the explicit startup stage. I'd have thought that everything would have been initialised by that point. Oh, well, go figure.
I suppose I could auto start the quest in an OnUpdate loop. I can probably auto start the first scene as well and then hand script the others to start. has anyone else found any useful strategies for dealing with this since 2012?
The other reason I wanted to post this: are people aware that the people over on www.gamesas.com are copying our threads verbatim and republishing them with the names and avatars changed? I mean compare http://www.gamesas.com/cannot-start-scene-because-its-parent-quest-was-not-run-t258379.html with the one I linked at the start of this post.
Is it just me, or is that a bit bloody cheeky?

Apparently I am secretly both "Louise Lowe" and "Matt Bee" :/
