Thanks for updating this issue Tosh.  I checked my iPad 5th generation and it is indeed working again.  I copied all of the Minecraft data back and it works.

I'm having this same problem on an iPad 5th generation.  I've uninstalled the game and reinstalled it and it didn't fix it.  I also completely restored the iPad to factory settings, only installed Minecraft 1.11.1 on it and it still didn't work.  This version works fine on my iPhone 8.

My daughter's 5th generation iPad running iOS 12.2 can no longer use Minecraft after the latest version was released (1.11.1) a few days ago.  I backed up the data, then deleted the app and reinstalled it, and it still didn't work.  I completely restored the iPad without restoring from a backup and only installed Minecraft on it - it still hangs.  Basically Minecraft no longer works on this iPad with completely default iOS settings and no Minecraft data. 

I have seen this happen, but not to zombies. I am seeing that chickens, particularly when jumping, will glitch through sand. Maybe it's something when mobs jump up a block?

I can confirm this, every time I used an iron sword to kill the largest size of slime and I kept getting hit and no damage was done to the slime. I had to resort to a bow.

I can confirm that if you place a map inside an item frame at one location and the remove it, and place at another location with the same map, the first green marker will remain until you exit out of the world save in single player.

I have also had achievements reset. As Levon stated, I also have not had achievement reset after updates. I would also like to note that I loaded a backup of my achievements into my folder and after 3 tries they were not accepted.
