I can't give fertibility pill to Cassie after getting Alissa. The game just breaks if I try to. What's up with that?
It seems that this bug was something rare, but it's fine now. Well, while we're at it, do you know how many interactions are there to fulfill "Hang out with Cassie and Alissa" quest? I reached a certain moment with Alissa becoming an actual pet, but the quest is still up and I don't know what else I can do.
