Not sure if this is a bug but its gotta be.
I was on ILS approach to Madrid and at about 2000 ft  it stopped following the localiser and rolled hard to the right so I just aborted the landing but the alt hold just completely failed it was just pointing straight up and no matter what I did it wouldn't level off with autopilot. I could hand fly just fine but whenever I tried to use VS to put the nose down it would just disconnect it also wasn't gaining speed despite being at full throttle so I basically stalled and that was it.
