Thanks for letting me know about those. I wrote my own script that creates an ultrastar file from a midi file and a lyrics txt file, because that was the workflow that worked best for me. I've been testing this with Melody Mania and using files generated from its editor as a reference. Either those did not have those line break timings, or I somehow missed them. I'll adjust my script to include them and update the songs I uploaded.
Last time I tried them they weren't synced to the video, at least with the download I used. To be fair I did not double-check before mapping the song, but that's why I had it mentally marked as "not mapped".
