I'm in r30 and there is 2 last things I have to do on my logbook. That is to hang out with Cassie and Alyssa, and help bell milk.
How may I finish these tasks?
For Alissa, you need to get Alissa to interrupt you and Cassie 3 times. The one most people miss is having to annoy Cassie (make her change clothes a lot. She can't be pregnant for this.)
For Bell, after getting certain number of cowgirls and renovating the farm, talk to her and you can bring her out to certain places!
