After a refresh (I had all the kittens and over 300 chancemakers with all upgrades, if that's important) I has no big cookie, and no dragon. I hit refresh and the game stuck on loading screen. After deleting cookies and reloading from an old save from 2 weeks ago, I had the big cookie etc. but no falling cookies and the milk display is corrupted (sometimes there, sometimes not). Everything else seems ok, but I have lost a lot of progress so maybe the bug is in higher levels.
