TBM and King Air Autopilot loses track on final

For several months I have noted that autopilots track routes fine until nearing the ILS final approach, then veer off. Hand flying to landing usually is successful. This has been noted with the G3000, G3X, and even a few times with the Airbus 320Neo. The most stable autopilot at this point seems to be the G1000 NXI. If other have experience the same, maybe we should make more noise so this bug can be addressed in the next updates. Otherwise, the 40th Anniversary edition is running very smoothly, no CTDs, stutters, freezes, dark avionics, etc. My experience is with an Xbox X.
