Storyline360 will not save because it says I don't have enough memory.

I too have lost HOURS of work due to the 'not enough memory' 'bug'. See this issue has been going on for years. Zero resolve, hours of work gone. Was about 27 layers deep in a slide and all of a sudden this bug. I'm down to what I had a few hours ago. I have 'auto recover' set to every 2 minute and clearly it was not doing that for a very long time. Super.
