People who have trouble autosaving, please try in a couple of days. I am monitoring this, but the issue is related to >Firebase< imposing a max of 20000 writes per day which has been smashed today, but this is because of the game being new and showing up more. Once it settles down it should be ok, but I am watching to see. I cant see this game hitting more than that many writes on a regular day, but if it does then I will upgrade the plan. In the meantime use the export save and paste the string in a text file.

You can tell if it has failed to save to cloud because if you look in the console (F12) there will be an error from Firebase stating the quota is exceeded, but this resets every 24hrs.
