The game doesn't explain anything very well really. In an interview I read online, the CEO admitted the tutorial at the start of the game was rushed and a last minute thought. The dangers in upgrading town halls, loot penalties etc should all be information readily available in the game. I used to think when I first started playing that if someone attacked me and I didn't get shield the buildings were still destroyed for the next person to flatten me easily with half the base already destroyed. Back then there were no replays and no info on what actually happened so it was anyone's guess how it all worked... to answer your question OP, nothing happens to the builders and they still run back into the rubble if it's destroyed.



Ewww....
