Farming

[Okkoto06]

So I have a guild member that's running into an issue with farming. For some odd reason he can only send out 3 waves of troops out at a time. If he tries to send more he gets an error saying that all his commanders
Are currently out. Wtf is this?? He has a level 20 barracks same as me but I'm not limited to how many waves I send..

How many different support waves does he have out? There is a limit of how many different waves a city can have out at once, support or attack.
