One thing what i am not sure about, and now its starting to make me think alot. Most of buildings, mostly lvl 3 i keep buffed for all the time, and if i do so, they make 2 times more x material, with only half needed y material. Like 6 B swords, with materials for only 3 B swords.. Now i was started to think about mines, and cant understand. If i have lvl 2 iron mines, each cycle they use 2 irons from deposit and gives me 2 iron ores. If i buff it, it will give me 4 iron ores per cycle .. but will it drain 4 iron ores from deposit ?
