Maurice - the other ZZZ37 pod does indeed have Galaxy Explosion (in it's cross) which is the exact same cross as one of the defective pods previously. I don't have any more pods bursting open like that.
I also have pods that seem to be rotting from the base of the pod (where it attaches to the scape). Very soft and squishy at the base. They seemed to be developing normally until now. I assume either bugs got into the pods or the pods (which are large) did not produce any seeds. (Like a false pregnancy.) It is interesting that the pods are quite large and still green like a developing pod, but they are starting to decay from the base of the pod upwards to the top of the pod. I have several different crosses doing that on several seedlings and registered cultivars.
Any idea what might cause that?
