I just started my 32nd generation in one of my families. Since my 31st generation had all the "symptoms" of the glitch mentioned above (no marriage proposals, says already has children though she doesn't, etc), I assumed that when my lady (Happi) grew old and died, that my game would end. However, along the way she adopted a little boy named Havoc. It showed him as her brother in the family tree. He grew up and went off to college, then she was alone again.

When Happi died, I was waiting for the message that my game was lost, but it didn't appear, so I looked at my family tree. It looked the same as before. I clicked on New Generation and lo and behold there were 4 people to choose from to inherit the home. One was Vista, one of Happi's sisters, TWO were Havoc, identical except for career, and the other was a female with no name. She did not look like any of Happi's sisters either, so I don't know where she came from. I chose this one to inherit the home and named her Sophia.

When I looked at the family tree after starting Sophia's generation, it looked just like it did before, ending with Happi's family (her parents and siblings). Sophia is no where to be found. It does not show another generation after Happi's.

So far Sophia has not received a marriage proposal, which I don't expect her to. It also says she has 4 children. I will see what happens when she grows old and dies.

I wonder if this ability to start an additional generation had anything to do with the fact that Happi adopted Havoc, even though it put him in the family tree as her brother.

Just thought I'd share the details of this interesting turn of events.
