I wonder what percentage of players actually reach the 30th generation and come across this bug? I'd think that many will have lost at least some interest in the game before then since it seems to take over six months to reach 30 generations.

I must say that I was beginning to lose some interest. With millions of dollars in the bank and not many challenges to be completed the game became a little repetitive. I still needed one or two insects to complete the collections and therfore the trophies, but I was in some ways re-stimulated by the challenge of re-starting the families from the beginning again.
