In my most recent game, we used 12 spies to sabotage a city with a bunker. It had a level 3 bunker and the spy report said it did 2,010 damage to it. As my troops approached a few hours later, there was a level 2 bunker. I cannot wrap my head around how any bunker remained. By my estimates 2,010 damage to a building is a lot. Any ideas other than a bug? It was a gold free game, so the level 2 bunker was not made of gold.
