I hit the button that sends all offensive troops to the bunker and saw them going to the bunker.  I then hit the button to send troops to the bunker, because I had too much defense at my base for this conflict. There were no offense at my base when i sent some of my defense that I had won  in battles just before logging out. There were over 70,000 troops showing on the  tracking tab at the top.  How could they be lost in an attack? thank you
