Amber - I have noticed the very same thing happening here. I am wondering if it is being caused by moisture/water. I have had to use my irrigation every other day this summer because of the heat. Typically the pods start ripening all over, not on one side or one chamber. I did harvest a few that looked like yours. The seeds on the brown side were ready for harvesting. The other (green chamber) seeds wound up shriveling and dying. I need to figure out a way to harvest seeds from just the brown side and leave the rest of the pod in place until it all turns brown so as not to lose any seeds (prematurely). Something else I've noticed is that that scapes are browning and crumbling, yet the pods are still green. I had to remove a pod this morning that had a collapsing brown scape. I put the entire green pod in a paper envelope to hopefully ripen without losing the seeds. Am hoping the moisture in the green pod will last long enough to produce ripe, mature seeds. I've never had this problem in the past that I recall.
