I checked the log file and there's no errors of any kind listed.
I suspected that a cutscene might be the issue and as such moved it to a section that is completely devoid of any funny stuff. It's at the start of a scene, following a standard transition, first action part listed in the 'At beginning of scene' action.
I'm trying to establish an autosave for new game "contition resetting" but I can't get it to save. I've also removed any checking for existence of autosaves -- I'm just calling Execute autosave #0 straight.
I can't really be more specific, as it isn't really in a fancy place in the structure.
