A320 sinking on approach after update? Not staying at requested altitude

@PZL104 Many thanks, your help is much appreciated.

  1. The A320 was covered in ice. I never turned on wing and engine anti-ice as I chose the setting icing - visual only, so I did not bother. Do you think this matters? However, I will have the next flights with de icing on and see what happens.
  2. I am going to check that next time I play.
  3. I do not know what you are referring to, sorry, I am completely new to flight sims (even though the plane never sunk like this before the update!).
  4. I heard about it, is it a different airplane? Where and how can I download it?
