Google Daydream SDK enable/disable crash

Dear Epic/Community,

When I use the Blueprint node “Enable HMD” and set the flag to false, the settings cog and line down the centre of the screen doesn’t disappear.

It will also crash the app, some of the time.

I am running it as a Google Cardboard app on a Nexus 9 and Nexus 5 running stock Marshmallow.

Regards,
James
