Unable to use controller to look up, down, left and right since 11/19/15. Using minecraft pocket edition on Amazon Fire TV. 0.13.0 alpha. I've confirmed the issue is not the controller.

Secondary observation: the game completely locks up/ freezes went attempting to use a sign. Also since 11/19/15.
