good point, I'm gonna let the game play in slow mode, following your explanation I wonder if I do not make my sims harvest too much too fast thus depleting the crops too rapidly (even if my food bin was only filled up at around 580 units). Since I'm controlling then I sometimes force them to harvest instead of goofing around ..... 2 options then either by just keeping the crops above 300 unit to avoid them to be "worried about food" but not too much I won't have the problem anymore or it rehappens and since I won't have enough food in the bin they'll die. Anyway I backed up up my game thanks to a toolkit I saw referenced on this forum, thus I do not take too much risks with my ongoing game :-) thank you again very much I'll keep you informed if you want
