Nether Portal - teleportation affects direction mappings

windows 10 Beta with oculus VR using microsoft xbox one controller (although also affects keyboard)

Following teleportation through a nether portal, the player spawns facing the obsidian blocks and the directional movement input for forwards,back, left strafe and right strafe become "twisted" relative to the portal entrance/exit direction. affecting both keyboards and left analogue stick input methods.

this can be worked around by saving and loading the save game.
