I am running a Windows 10 fast computer 6800 Raytheon card and great FPS but did an IFR flight in the UK today with plan made up and approaches  from LNM  but after landing it into FS2020 the program deviated me from the LNM flight plan and discarded the STARS approach I had chosen and directed me straight to the airport. Curious about how that happens??  I would love to have LNM control the whole flight after loading into MSFS2020. BTW I use ECHO as well as an autopilot controller and it is amazing. Ended up cancelling IFR before arrival and doing an illegal VFR landing with 500ft ceiling in heavy rain. 

AIRAC up to date?

• If you use the Navigraph update for MSFS: Update the Little Navmap database with the FMS Data Manager as well to keep the program in sync with the MSFS scenery library. Use the scenery mode Use Navigraph for Navaids and Procedures in the menu Scenery Library to get access to all procedures in Little Navmap.
• If you do not use the Navigraph update for MSFS: Use the scenery mode Do not use Navigraph Database in the menu Scenery Library to avoid issues with missing or changed navaids. Keep in mind that SID and STAR are not available yet in Little Navmap.

Load of flight plans MSFS is quite buggy in general.

Thanks for both replies, I have the navigraph latest airac data and have gone through Alex' suggestions, have yet to try it out again, but I do agree there are some buggy flight plan uploads. LNM is amazing though. After  40 plus years of private and commercial flying I find this almost as much fun!!!
