If you go in the pvp entrance, and while your character is "entering" (Loading bar) You can press the elixir button, and you can see your elixirs. That isn't the bug. The bug is when you don't close the elixir screen, and you enter pvp. In pvp the Elixir screen and button is gone, (not a bug). But your joystick is gone and you can't move because there is no joystick. (That's the bug) :P So yeah...
