I can't figure out where the save points are.
When I close the browser and restart, I loose several levels of mastery.
Just now, the game crashed from an out of memory error (the game has been running continuously for 3 days). When it came back I was 3 levels behind where I was.
Can I force a save?

Should save every 20 seconds at worst, plus saves when you do something like level up. What OS/browser?
