Whats with not being able send friendly challenges amongst clanmates within 24hours of your base being modified that seems rather annoying and pointless to me how else do you get input from clanmates if your base is working properly .. In my opinion this update is GARBAGE
Friendly challenges have been like that since they were introduced. The reason is so that in war you can’t copy an opponent base and practice on it until you can 3 star it. If the cool down wasn’t there, this would happen all the time and war would be meaningless.
