Lo-Fi Games

I've built 3 cook stove at different places but anyway, my peons are unable to use them correctly and seem to fail 10 to 100 times before finally reaching a position that allow them to use the stove. This is a bit a game breaking issue as it can easily kill a colony by starvation.

Edit : It looks like it happens when there are various permanent orders. For exemple I set first cooking, second, making bread, third making flour. At a time it begins to fail hard as the game seems to be overloaded by priorities...
