ETA: I made a short video to demonstrate this issue.
I love the Wormhole cubes and can't get enough of them! In solving my new Wormhole III, I've encountered a case that I have not seen before. It makes me wonder if it is also possible on the Wormhole II. Basically, I have one pair of flipped inner edge pieces, as shown in the left photo (sorry for the focus, I am getting a new camera).

On the regular Wormhole puzzle, this would be a simple case of applying one of the inner edge flipping algorithms twice. Oh, but the Wormhole III is devious and the Wormhole edges (the lovely peepholes that expose the whole other puzzle inside) cause bandaging when they are substituted for Mixup Plus edges (as shown by the arrows on the right photo). The net result is that all of the inner edge flipping algorithms fail - at least the ones I know about. I've tried adapting them, but there are only 4 Mixup Plus edges and 8 Wormhole edges, and I just can't find a way to position things to keep the Wormhole edges out of the way.
I've tried everything I can think of and I'm looking for some new ideas to flip or flatten this inner edge. Theoretically, this case was covered in this previous thread
, but unfortunately... it did not reveal the solution. I'm particularly curious to know if this can also happen to the Wormhole II - I've never seen it - or if it is the result of a unique quality of the split Mixup Plus layer on the Wormhole III.
