Tried going there sunday 00, nothing to interact with. As for odd months, i know that from walkthrough, i even used cheats to advance days to odd month several times just to interact with her and try everything i could, still nothing. I would post my save but i doubt this thread has significant interest so someone who is knowledgeable would try to check it and see what's wrong. Olivia is not an issue now, it would be in the future updates if her path completion is required to progress with other characters. But we still don't even know if we're ever gonna get future updates and when.
