teleporting out of battle, related to broken "Scout"?
I just had the same thing happen to me. First time I thought it was a glitch and I tapped on something wrong. The next two times were DURING A WAR BATTLE! The only thing I could do once I had teleported was return to the war map, and the battle treated it as if I stopped dropping troops.
It's now happened 4 times in the last 15 minutes. I wonder if this is related to the broken "Scout" button - someone else is trying to "Scout" and instead it's sending ME to their base.
