I've found a culprit

Imho someone from Ableton should address this but at least i've found what is causing my notes/sequences not to be recalled on each project load. And there is a workaround.
Solution is simple and you'll have to watch only on one thing. You can't have "edit to" enabled when you are saving your project. So beware and make sure that "edit to" is disabled and not lighting. You can have it enabled and work with it but when you are done be sure to DISABLE it.
For some reason if you have "edit to" enabled and you save and reopen project all your notes are messed up. If this is disabled you can have as much as possible patterns saved correctly, with all kind of variations, etc.
Great but imho this need to be addressed. Not everyone is reading this forum..
