Weird, I loaded an older save and Lisa is no longer pregnant, yet im still on the island. My 'title' also reset to 'Master'. It also seems like my name reset to Ryan, but im not sure, since this isn't my first playthrough.
It's just a visual thing, you'll be able to do so again right after getting from the island.
Reloading a little older save, it seems like the dialogue changed a little to explain the thing with Lisa. So no problem there.
