Dear OutsiderXE,
Regarding your last post. There is a goodway to deal with such thing (other than backup ofcourse).
what I started doing is, I put the "To Be ChangeLog in Next version" and put it in my map description before I upload the actual update. I keep update description of each change in detail, small or big. This might help.
though I can imagine if you wrote long trigger, especially if it was cinematics.
