That happened to me in my PC when I had Windows 10. Download the old launcher and everything will work fine!
Updated the versión list.
Updated version list. Still present in 15w34c
Changed the title, I mean shields cannot be enchanted inside Enchantment table
Can confirm for 15w33c.
It may be caused because of shields cannot be enchanted on enchantment table. I guess
Added a video.
The explosions that break blocks outside the world border are also "Works as intended"?
On other snapshots the world gets generated but not updated...
Confirmed for 14w28a
This is not a bug, you have 'reducedDebugInfo' enabled.
Type /gamerule reducedDebugInfo false and you will see the coords.
