dissapering orange battle line

had an incoming attack today, put the proper defenses in place. waited till it hit but then the orange line with the coming time was gone?!

so thinking the army had witdrawn or something like that send all support away, closed dolumar.

30minutes later online again seeing in the logs i lost 14 runes because there was no defense and the attack happend later then it should????

this is bad if you cant see your enemy coming, especially if you send your troops away because you have no orange line that says incoming attack!
