I made some drawings and saved the file on my computer. When I opened it again, the rollback bar shows the line in the middle of the "timeline" (and, of course, an earlier version of my draw), but I can't pull the line back to the last thing done, so my object become integer again!! I've tried Ctrl+Q too, without results.. Can someone please help me!? (Solidworks 2016 here)

I attached a PrintScreen of the problem
