The attacker sent waves from 3 cities to land at same second. All waves showed up in enemy tab with in 2 seconds like 6 waves popping up from 3 cities.

If it was camp time in my enemy tab i should see waves coming after 3 or 4 seconds atleast, but here it was like in 2 seconds i see 6 waves coming up in enemy tab from 3 cities all hitting same second. I was looking at enemy tab as the waves started coming up and so i am sure it was not the normal camp timed waves.
