If youre on PC just check server details. Not sure why that info isnt available for mobile honestly. This game needs a lot of balancing for mobile players if you ask me.
I'm not even storing anymore, it was a necessity thing 5 days ago I started a couple days late and had pretty much full turns and was having trouble spending them. Having not played team for a while I couldn't remember how many turns I could store... I'm using the turns now, don't worry I'm not planning anything... isn't there something more interesting going on in team ATM that we can discuss instead??? :)
