Dec release upgrade...PI going to sleep after a while

PI with OSMC was working flawlessly before… ran upgrade to Dec release (thanks Sam!) and now after a little while of inactivity it is apparently going to power-off or sleep… Hard power reboot, it comes back fine… I thought it was CEC so I disabled that, but still have same issue… What am I missing?

Nothing has changed on the config (or TV, or anything…) except for pulling the update to Dec…

Any help much appreciated!

Thanks, gents!

Just reloaded image…seems to work fine now. Thanks anyway…
