Your list from yesterday has 11 GEO1k files and 9 1000m files. NOT expected.
Your list from today has 10 GEO1k files and 11 1000m files. NOT expected.

1) You either look too early and the files are not in (as I just explained to Douglas).
2) You simply didn't receive all FY-3D files on HVS-1  (use TCLogSummary.cmd)

Regards
Ernst

P.S.
My two receivers with a TBS-6909X taking all 3 services with 3 demodulators
have not lost one single UDP packet (and so no files) for the last three weeks.

Be sure to give enough time slack for the data to arrive. If you already had todays picture before your last post then the timing may be tight on some days. My scripts
do not know when the files arrive. They do not predict passes but they look at the available file names with segment times and reverse calculate the orbit positions.
For todays almost overhead pass the last file was 13:17 UTC but yesterday (as the nearest pass was more west of IsleOfMan) it was 13:36 UTC and this can even be later.
You have to add an additional worst case slack of 50 minutes (half an typical sun synchronous sat revolution time) to the time of maximum elevation of a central pass.
Then you have EARS timelyness which IIRC is up to another 30 minutes. If you make a picture while data is comming in you could end up with a list of unpaired
1000m and GEO1k files. Then simply try 30 minutes later again (remember FY-3D has LTAN 14:00 which is also 30 minutes after NOAA-20 and Suomi-NPP).

This looks as if you do not have some data that are needed for "true-color". Maybe some VIS data is not transmitted far north in the dark?
1) Can you give me a date and POI location and range you use that shows this problem (I have data 4 days back here) ?
2) Can you try a FY-3D IR (DAY!) composite with these input data that does not produce a VIS (DAY) "true_color" image ?
3) Can you have a look at the list [bestfiles] or use good old TCLogSummary.cmd to make sure you have no missing files?

no problem here under GNU/Linux. The FY-3D files come in pairs 1000m and GEO location.
Not sure what happens if you are missing one file in a pair. Try to print [bestfiles] in the script.

I doubt there is a problem in my simple pass seeking code. If you change the POI this may result in another orbit number.
If you only increase search range (ran) the pass will be "longer" and maybe reach far north in the (November) winter dark.

I just had a look at U.K. passes of Suomi-NPP, NOAA-20, and FY-3D from the last four days.
11 passes are fine, todays NOAA-20 orbit 15565 shows the old problem again. My bet ist that
this is a software bug in the code that stitchs together the data from LANNION and SVALBARD.

FYI:

xrit2pic 2020.4 is now available, for Linux, Windows and Raspberry Pi (last one only command line version).
Supports now also FY3D (just "fly-by" picture), and MSG native format. With a simple python script it is now possible to download near-realtime HRIT MSG/MSG_RSS from the Eumetsat-site, and process it using xrit2pic.
Works fine on a very old RPI (2011, I think one of the first versions).

Hi Christian

Thanks for your help. I put the following in the generic.yaml in the enhancements folder

night_test1:

    operations:
    - name: inverse
      method: *inversefun
      args:

    - name: stretch
      method: *stretchfun
      kwargs: {stretch: linear}
    - name: gamma

It sucessfully created inverted images combining M15/M14/M12 for descending passes NOAA20 and SUOMI NPP today
