Good morning
I did an oblique mission with my DJI M300 RTK using DJI Lidar camera (so total of 5 flights), aslo using DJI D RTK 2. After the 2 first flights, I had no RTK signal anymore from the base station (even if I moved it). And because I could not take off, I decided to turn it off and did my last 3 flights.   

Back to the office, I wanted to process my flights into DJI Terra but only 2 of the 5 folders were recognized. I found that the 3 last flights do not have .RTB file in the 3 folders.

What should I do to process these 3 last flights please?

Does it mean I can do Lidar mission without DJI D RTK 2 base station? All terrains are not flat and sometimes using RTK does not work...

Thank you

You can simply process the data as PPK instead of RTK, if you can access RINEX files of your area.
