My flour canister is from last year, but my pancakes could put a marathon runner to sleep. I follow online recipes to the letter, and they still turn out flat and sad. It's a talent, really, just not a useful one.

That "doing the right thing" part always gets me too.

Screeps popping from attic temperature changes is pretty common. Just screw them back in and patch over the spots. It's only a real problem if dozens of them are coming loose.
