I wonder if its possible that the saddle is to wide??( since you said her roundness got better) I know nothing about this, im just wondering.. Since you can't get a saddle fitter. I was trying saddles once and I had a really nice one on trial. Turns out it was to wide, cause it slid off easily. Im sure there are videos out their that show how to check for saddle fit-English though. Since saddle fitter is not an option that's what I would do. Also, horses change. The saddle might have fitted when it was fitted but it could not fit now. It happened to me once. Does the owner know its slips like this? If not you should mention it, maybe they can do something about it.
