With one of my XL4 files, when I change some NC effects in it then re-save, I "lose" my imported LOR info that was previously contained in the XL4 file. In general, I am opening up the file in XL4 sequencer, rendering, saving, then going to the preview screen to "watch" the sequence. In one case, I re-converted my LMS file again and re-saved but I still don't have any of the LOR info there... This particular case might be an isolated one because some of the XL xml sequencing that I KNOW was there, I had to add back in... Using 4.0.18...
