Back in one of the VV1 suggestion threads I thought that a hut being destroyed (or other building project) would be a "good" event. It would certainly give the builders something to do!

I agree that destroying the dam would be very interesting. The farm would go away (and the crops damaged) and that would also affect the food supply. Plus having to rebuild the dam and clear the mosaic...

IMHO, if a hut is destroyed, then the villagers start weakening until it is rebuilt (if the population is over the maximum allowed...)

I hope that VV3 will include events like these. (I tend to always chose the more "interesting" choice to give the village or the villager more of a challenge...)
