I tried this for the first time and was enjoying it so much I wanted it to go quicker! I had 12 adult villagers and 3 children, and was waiting getting the hut built so couldn't have any more babies yet - I wanted to go to bed and set some babies growing! As I had seen on here that you could change the clock on the palm by an hour or two to advance the game, I did this a couple of times and it seemed fine. I had done this before with fish tycoon, and it worked fine. Unfortunately I then did it again and it all went horribly wrong!

I had advanced the clock by 2 hours (from 11pm to 1 am), and nothing much seemed to have changed - but when I put the clock back to the normal time a couple of minutes later, all but 6 of my villagers had died - but the food had gone up a lot and so had the tech points!

Its like it had advanced way too far, although in fact the clock had gone back 2 hours!
It was going backwards and forwards past midnight, so I wondered if it maybe it thought it was a whole day gone by, instead of going back a couple of hours. The clock was definitely right on the palm though, and so was the date.

Anyway, just thought I would let you know, in case any one else had the same problem!
