This happened in a Jumpgate game. All but one rectangle that I had drawn on the Map Layer of a page (using the Rectangle tool) had disappeared after logging in to the game today. When we left off last week, they were all still there. Took me a while to realize I had to select each one of them once to make them visible again (thankfully I realized to use Ctrl+A). I loaded the game in Chrome and Firefox and the problem was the same in both.
