13/13 drones shot down, two buildings hit
The buildings crashed into the remains of the drones, obviously.
The problem with the Shaheds (and many other cruise missiles) is that:
1) The Russians target civilian infrastructure/buildings with them.
2) The Ukrainians tend to shoot them down (or not) over cities, so they inevitably fall on something civilian anyway.
Result being that Ukraine can claim they shot it down even if they didn't and Russia can claim it hit the target even if it didn't.
Regardless, Ukraine has an energy crisis today, and they didn't before the drone strikes.
