I too got a rotten Anaconda bulb. All the middle scales dropped away and there wasn't anything there to save. Some outer scales were still attached to the basal plate. I washed that part up, keeping it intact. After air drying I popped it into a baggie of growing mix, covered it up with more mix and set it aside. I really didn't give it much thought since then (around the same time as yours, Lorn). Now I am seeing roots around the inside of the bag.
The other two bulbs were good and each has put up two stalks.
