Accidentally loaded a D12 when I intended to load a C11 booster. Realized the mistake when it took forever to stage. Lost sight of the sustainer for a while but located it in the sky under parachute after the boosters fell. The following day I got permission from the owner of an adjacent field to search for the rocket and found all the parts! Looks like an animal chewed on the fins of the sustainer but it is still flight worthy.
