Reposting my post from Diverse since this fault belongs in this folder.   Problem: Whenever I reload the aircraft, the left CDU stops functioning. Identification of the problem: The top of the initial page on the left CDU says: "A0-0, Eng Unknown". The left CDU is non-operational - you cannot switch pages, and you cannot enter data. The display is working, and showing nav airac cycle. How to reproduce: Reload the vehicle from the p3d v3.2.3 vehicle menu Frequency: 100%
