[Bug] Opponent's buildings get destroyed when he surrenders

Opponent surrendered without leaving the game. Checking the map revealed most of his buildings having been automatically destroyed.

not a bug, its intended

This is the only match where it happened. Usually it’s just the Landmarks.

And even if it’s intended, it’s bad because I wanna be able to see what buildings my opponent had and where they were placed. What’s the point of revealing the map otherwise?
