After saving a pic in PS, returning it to LR, The created TIFF picture dosen´t show in LR, next to the original RAW(NEF) pic, until I restart LR.
I´m running LR & PS CC 2015. Updated to WIN10 a few weeks back.
Could you please set Photoshop as an Additional External Editor in Lightroom and then try to save an image and check if it comes back in Photoshop or not.
Also make sure you should have the option stack with original checked.
