Just saying, though -- there is nothing to do when this occurs. I've seen this when I restarted LMMS and some loops are deleted (at least 2 of them) and I don't know how that even happens. This occurred in some of my projects with very long loops or sometimes a single loop with so many notes. (And I got annoyed when the melody part with a complex note pattern got deleted) Even loading automations and note patterns are now loaded properly in rc-5 comparing to 1.1.3, this might have added when the loading stuff in previous versions were debugged. That's why... keeping the .bak files and always save project to new version is an essential habit
There's another similar part of this, that when you opened the project after restart the loops will disappear, but when you click the part in song-editor that's close to the hidden loops they will show again in the specified track.
