Noticed something was up with explosive charges last weekend. Now that I've had more time to experiment, I've found that, when detonating explosive charges simultaneously, only the first charge you select explodes at full strength.
Box 1 shows what you get when you detonate the charges individually, in sequence. Box 2 shows what you get when you select the bottommost charge, add another charge to the selection, and detonate them both at the same time.
