One thing that keeps bugging me is how my armies can be kept hostage in a war two other players are fighting. Just happening to be around the area where a fight is started freezes by army or even armies there under the fight and I'm not able to move them. 

It really should throw outsider army outsider of the battle area borders. 

I also hate when that happens. I think we should be able to "retrieve" our army in such situations !!
