Food, coins and wood is double in CE. If you freeze the result at a high value (like 500 or more) , the ammount will not change, BUT it will increase much faster than your normal rate. This will happen only if you have positive income and it helps to hoard resources fast and buy iron, stone etc. But you have to freeze only the "real" value, the one with multiple digits otherwise the game will crash at some point. If your resource income is negative it will not rise but it will NOT go down either (it will go down if you buy something with that particular resource=land with food, build with wood, buy stuff with gold). It is some kind of cheating, not perfect but better than nothing. You just have to keep your resource income positive and the game will be easier.
