Game is now completely unplayable. 😞 Not cool.

Now crashing on Android version. Latest update of game from today's date. 1.2.5

No.reply from Mojang on this issue. I'll be miffed if my world is borked because of some game bug that never gets fixed.

I've just updated to the Fall Creators Update and now I have a similar issue.
