dont know what happened but my game has gone back to the begining,i still have all my tech points ,have everything except nature 3 but the game shows no huts built,no erect statue even the sundial not there,all my collections are still showing as collected,my skilled farmer is fishing among the sharks but the unskilled jump out saying "eek sharks".
i have no children and only males,is this why ??

try here VV1tycoon had the same type of problem.

thanks deathwing,i looked at that link,must admit i am not technically minded,looked for the file mentioned and couldnt determine which file i needed.if i delete the game and reinstall it will i lose everything.my son also playing on different user,his is fine.

Did you look at the FAQ answer that Barbara linked to in that thread? It gives details about backing up your savegame files and restoring them if possible. As deathwing says, your problem looks like an issue with the savegame files, not the program itself, so there should be no need to uninstall and reinstall the game.

Even so, uninstalling the game doesn't necessarily remove the savegame files; that needs a separate operation.
