Well they did say that they could not promise that snapshots could not be updated so on that my test may be flawed.
I have a world saved in 18w16a and when i opened it in 22c all the air blocks were still present. So I believe that there is still a problem.
How do you back up worlds?
It finally updated to 1.4.2 today. Six days after the release date. App store update had to repeat I guess, maybe a failed attempt.
Thank you for your help!
I am using OSX 10.8.5 and see the wolf problem, but not a problem with Ocelots.
I am running on MacOS sorry for the confusion!
This is the bug that stopped me from playing. It's pretty reproducible and makes your world swiss cheese.
