I watched this guy eat bread for ten minutes. Then I tried to jump on his head, and was thrown into nothingness.
Some helpful people suggested I try the /reloadui command. This did not work. Another suggested /stuck, which killed me, reducing the durability of my items, and then respawned me back into nothingness. Several people suggested I buy gold or powerleveling services, but I failed to see how that would help.
I decided to restart the game.
It's been spinning like that for a while. I forcibly close the program several times, but kept coming back to this. I'll check back later.
The moral of this story, of course, is you never try to get between a man and his never-ending loaf of bread.
