#1 Hi Tali, say, for example,

Hi Tali, say, for example, you need to produce 2 timber. For that you need 6 logs, 3 each for 1 timber. If you have 3 production logs and are just beginning the game, each slot will produce 1 log in 3 seconds. So, if you start 1 slot of logs and then quickly swipe down to your timber slot and try producing timber from that slot, you won't have enough raw materials. Just give it about 10 seconds before you produce timber. Alternatively, when enough raw materials are available, the timber will start producing automatically when you double tap the produce button. Hope this helps!
