I have LR 6.1.1 on a windows 8.1 PC and I've noticed lately that I now have jpgs listed in the catalog, when I only import .cr2 and from there I'll edit further in PS CS6 and create a .tif file which will show up in LR.
What I do not understand is why the jpgs.
Also upon further investigation I've notice a lot of the files have renamed themselves to either:
I've noticed these seems to affect images shot in 2009 and some in 2010.
Also I've noticed that some the image (a small few of about 5) in certain folders will have half of the image gone or what looks like a corrupted image. These were not there a few months ago.
I know because I was working on some of the images and none of the images had any flaws.
