I spent most of yesterday learning how to fly the A350 (pre-update) using MS2024 without any problems.  Then later in the afternoon I noticed I could not load a any flight even C172, selecting an aircraft and airfield in the in map screen then pressing the 'Start Flight'   The airfield would load and I could see buildings slowly loading in the airfield but it would not zoom to the plane just a spinning circle in the bottom right of the monitor.

I thought no problem I'll use MS2020 to carry on learning the A350 only to discover the MS2020 icon on my desktop was missing (its been there for four years).  I went to the Windows Menu to load MS2020 from there, it started loading ok then went to the update screen and started downloading the program again 136GB.  I then checked the main Packages 2020 folder and it was empty apart from 4.3Mb of data, also my Community folder was empty.

I did not update anything prior to this so why did MS2020 uninstall itself - anyone else had this?

Just spoke to my brother who has both MSFS2020 and 2024, told him about my MS2020 disappearing from my computer and he said the same thing happened to him about three weeks ago, as he no longer uses 2020 he didn't worry.

Strange how both of us have lost 2020 without us purposefully uninstalling the sim.
