ok, has this ever happened to you? I was playing the game fine and then allof a sudden I went from 18 people to 3 kids and 2 adults..then we went to my sons game and the same thing had happened to him. What the he**??

2nd thing- how do you build up tech points faster? At this rate I will never get level 2 and 3 in things. I guess maybe I am impatient?

Were your people sick and you didn't notice it...? when last had you checked their health bars? Did you have an event? Had you left the game on 2x without enough food, or ability to get food?

Perhaps if you could give a few more details on what you were doing, food, health etc it might be possible to figure out what may have happened

no I was on the game when it happened, I opened the gong encasement and then it said the allergies are bugging your people, I clicked ok and then they were all dead. They were healthy prior to this and there was plenty of food.

I haven't come across that result of ringing the gong, so I'll leave possible solutions to LadyCFII

Without more details (like the log file and information about how long the game had been running, etc.), it would be hard to say for sure. There isn't enough information to do more than guess, but this sounds like the game was opened and the puzzle completion message was presented, perhaps followed immediately by an Island Event (the allergies). Depending upon how long the game had been off (and other circumstances, such as those bajantara mentioned), it's possible that such a thing would happen.

Do you mean you completed the clearing of the thorns in front of the gong? As suggested it is likely that your farmer/s got sick or were somehow unable to provide food for the tribe while the game was off. What were the food stocks shown in the bin?

The allergies island event has no real effect on the villagers, apart from making them sneeze in chorus.
