So I am at the part where I am supposed to increase the relationship of the girls to level 2 but they are no where to be found. I can only encounter Sy in the morning who only says "hi", Amy only in afternoon to spend time with her or go down on her, and Rebecca to take a break with her or walk her home. Should i start a new game or something?
That's exactly what happened, the previous quest (Soul at the shopping mall) is bugged and is completed if you do some activity, for example: sleeping, ordering something at the coffee shop, etc.
There is a fix but it apparently only works on new saves. I'll add yet another fix for this bug in v0.2.0.
Thanks for reporting it and I'm glad you were able to figure out a way to avoid it!
