[ARCHIVED] [IL] Turtle Hatching, Event Not Happening

I have the same issue. I used to be able to see the turtles just fine but now it never works. It's very disappointing because the Island events are a big reason for purchasing this expansion pack. 

This has been a problem in my game play for several weeks so unfortunately I can't just go back to an earlier save - I'd lose (human, not Sim) weeks of gameplay. Turning off my mods doesn't seem to make a difference.
