This error occurs on the iOS version (IPA) EVERY time I request troops, change my main base layout, try to fill up eagle artillery and train troops on the builderbase. This hasn't got anything to do with my internet connection. Any solutions?
Will this be developed in the near future by your team? If so, when will these features be released because I really need builder base matches to practice with troops as I play coc primarily for the builderbase.
