Hey Everyone,
In 1.7 they added a feature where swords cannot break blocks in Creative. Now, In 14w33c, they added Armor Stands. I saw that swords can break Armor Stands in creative, but not any other block, including banners. I came across this bug when I broke an Armor Stand in creative, and it broke. Then I realised It happend and tested it on a few of the newer blocks and saw that this bug only works on Armor Stands. I then decided to post it here, on the Minecraft Bug Tracker.
