How do trained troops filter down to the army posts? I have tried training the same number of each unit type each time, but what makes into my army posts is a random combination of units. Eg sometimes I will have 20 bears trained, but what makes it into the army post might be all basic soldiers. So I expect the bears to make it into the army post the next time, but might get only one or two. Then eventually I'll get nearly all bears! ...very frustrating. there must be some system to troop replenishment? Pls help!
