Once I entered the end, I tried to jump off the obsidian platform I was on and die. But once I felll I just floated there, as if I was in creative mode and I was flying. I WAS in creative mode, but once I switched, it didn't fix itself, and now every time I try to jump to my doom, I end up floating, and then I am kicked off of the server because "flying is not enabled on this server". Thanks for reading this.
How to recreate:
(1) Go through the end portal in creative mode.
(2) Jump off and try to kill yourself.
(3) Change from creative to survival and you still won't fall out of the world.
