On Mac I got saves partially fixed (autosave did not restore) by replacing contents of "./Library/Application Support/Google/Chrome/Default/Pepper Data/Shockwave Flash/WritableRoot/#SharedObjects/6XU9LXX2/chat.kongregate.com/gamez/0016/7318/live/EBF4.swf" with "./Library/Application Support/Google/Chrome/Default/Pepper Data/Shockwave Flash/WritableRoot/#SharedObjects/6XU9LXX2/assets.kongregate.com/gamez/0016/7318/live/EBF4.swf"
P.S. Blame Kongregate for misplacing the game's SWF file
