I have this callout block and I've got almost all of the kinks worked out. I'm just having problems with the flips. When I try to flip the point parameter rather than flipping around the flip line it instead wants to mirror, along with its subjects, around the base point. I tried moving the base point to the intersection of the two mirror lines, but this causes even more bizarre behavior because it needs to move in order to stay centered when the block stretches. Any ideas?
