I'm still having trouble with starting the "Sectoral movement" quest since i think version 0.83 or 0.84. I already completed the "silky powder" quest, and none of the trigger events in the quest trigger. Any advice? I would prefer not to have to replay the whole game from the beginning if it can be avoided.
I am not sure , but you can try the following 2 methods first
1) Check if you have any other girl's story lagging behind (silky powder is for moth girl, maybe some other girls story progess has not yet reached certain criteria, if my guess is not wrong most probably Taile)
2) When do you try to trigger the sectorial event, some events trigger at morning or noon while some other triggers at night, maybe you are trying to trigger it at wrong time.
There aren't any clickable options in the core room for me, also i tried talking with Taile as her hint is "Complete 'Core recharged', and when Taile is recovering, see how she is doing". But i also dont have any talking options with her other than work, shop, and leave. and nothing triggered for me when i tried visiting her shop or my room at any point.
