Your honor, I think I know who bricked my window. It's the person standing right outside it.
Either that or it's the crab that does 60 damage to you.
Only real errors are sometimes with the UI stacking but it's not fatal. i.e. I had the "choose 1 of 3" menu up while in combat, and the card then didn't show up for that specific combat, and also I could pick all three (but it only added the first one chosen, as you'd expect)
