I also reported a bug a few days ago, but didn't get a reply, not sure if you have read it. I believe that pregnancy is not possible for Cassie if Olivia already is pregnant/shows signs of pregnancy.I fixed this bug. It will be available in the next version. I made the Cassie escorting to the new camp task mandatory. E.G. you won't be able to venture in the swamp if you didnt get her to the Cliffside camp first.
Is it now possible for Cassie to get pregnant (with belly) and birth for both girls? do we really need to skip forward until they reach regular birth time?
