Mushy is not good unless it's a fully ripe pod. A ripe pod is between 8-10 months old and will start to split down the center. It could be a pod from last year.
If there is any dampness present I would liberate the seeds from the pod right away. They are either over-ripe (in which case get them out of that pod or they will rot) or under-ripe and then they will not ripen any further off the tree.
