Getting "Raid" instead of full victory

I periodically (1/10 or 1/15) get only a “raid” instead of a full victory.  At first, I figured I was just missing a tower somewhere.  However, I’ve begun paying more attention recently and just now, I reached “raid” in the game, opened the doors with 15 seconds left, and the blue bar was totally full, but I did not recrive a victory ranking. 

 

I used Cadmus without spindle equipped.  I spawn troops all the time, including some archers, and should not miss any towers. What’s the deal? 

probably again miss a tower ?

Hello TheDon,

Could you please let us know if you attacked the gate with your Hero as well?
