You need to do all the scenes where Alissa intrudes on the two of you. For her last one, trying 'annoying' Cassie XD.
Multiple Cassie impregnations is likely a bug! Alissa cock blocking you from impregnating Cassie is intended XP.
Thanks, I will!
I did the first scenes in the bed & bath in which alissa intrudes, and now it doesn't let me call cassie anymore, and I can't talk to her in any way, how do I annoy her..?
