Hi Bulva,
I also have the TPR, it sometimes surprises me as the toe-brakes are gone, but never the yaw/nose wheel steering.
In the case of a toe-brakes loss I unplug and re-plug the TPR and the toes are back.
For our MuMu I removed the aircraft folder (by hand) and reinstalled it, then the nose steering came back.
I've also seen the throttle challenge where a long press on the bravo Toga button makes the throttles jump out of sync.
Will try the 1 axes throttle (thr5) on my next flight and see how that works with double props axes.
