M11-P missing pairs of DNGs on internal storage

Have owned my M11-P for about a month or so. Had a weird thing today. Took a few hundred pictures at an event. My standard setup is to store DNGs on the internal storage and JPGs on the SD card. When I got home I discovered I had 12 more JPGs than DNGs, with what looks like 12 corrupt files (0 bytes) on the internal storage. The 'missing' DNGs were spread over the day, but always in pairs - ie, two adjacent images would be missing/corrupt. Haven't seen this on prior shoots. Anyone else seen this and have an explanation/solution?

This happened to me yesterday. My camera is set to save RAW files to the SD card and JPEG files to the internal memory.

 

The RAW file is on the card, but it appears corrupted. The JPEG file was captured successfully. I guess there is no solution for this issue at the moment. I hope Leica releases a firmware fix to address this problem.

I applied the 2.1.1 firmware update. Camera seemed to be behaving. Now I've got a new problem. Still shooting with DNG to internal memory and JPG to SD card. Reformatted both before starting. On my latest shoot it failed to record one of the DNGs (the second frame shot) but once again recorded the JPG. However, this time the DNG numbering isn't missing one sequence number (ie, the next DNG recorded had the number that should have been given to the file that is missing). The result is that now all the subsequent DNGs are one digit out from the equivalent JPGs. This is really stupid and will ruin my workflow until I reset the counter at the begging of 2025!

Actually, scratch that. It's even weirder. I looked separately at the folders on the internal memory and the SD card again and the number are in sync, and the missing second frame DNG is there. It is actually the last frame DNG that is missing. I looked again at the PC folder I'd previously copied them to and confirmed what I'd reported above. Somehow, the first copy over to the PC produced a different file numbering result to the second. How is this even possible?
