Help - V1.0c appears to be buggy.
New to game - give 3 aphrodisiacs morning, afternoon, night - this part ok
BUT after 3rd aphrodisiac - you get fired back into your own room and it is impossible to "chat" with Elaine at night. Any attempt to move out of the room immediately triggers you into the next morning - seems to be stuck in a process loop - unless I am missing a way to find elanine and give an aphrodisiac in the 'late morning'
Alright, did a quick play though (Aka started a new game and saveeditted day/time) to see if there is/was a problem, and I was able to do this event, thus it's probably how you followed it.
-- From your post, the most likely problem is that you missed one of the instances and gave her one at night, rather than following the sequence of giving her one Morn>Noon>Evening, and then talking to her at night. The quest has to be done and completed in one day, or it'll reset. (Aka, she masturbates and the apo wears off)
-- If you're having trouble finding her, she's usually at home for the most part, besides after school finishes (aka Noon/Late morning), in which case, she's either at the plaza/square (left map) or at the store.
Some observations on the quest.
Edit: Adding some key words for others: Elaine, mom, night, talk, aphrodisiac
