Reports tab not flashing when under attack
I capped a city today, and it was attacked 3 minutes later. Loyalty was raised, however it was capped at the time of the hit.
The wave was a lvl 10 npc farming wave, which the owner admitted was sent out by his bot.
So here's my question. My reports tab never flashed telling me he was attacking. I had no knowledge of it at all until it was too late. Even more so, despite raising loy, the city was still capped.
Do you think that this is a glitch in the game? Or is it a part of normal gameplay that the city was capped with no warning, despite having more than 1 loyalty.
