Disappearing Brush Strokes

My brush was on normal but it was a viewing problem. For me it was the "highlight layer" option. See the pictures

draw on a new layer

Go to Brush mode, paint normal

Hello,

I'm having this same issue, but slightly different. Not only is this happening while I'm working in my file, but last night I saved after working and upon re-opening the file today half of it has been ruined with disappearing lines & fills or black fill bleeding into parts it shouldn't be. Last week I had a file that simply reverted back to an old save point after I'd closed and re-opened. Not sure what's going on lately, but it's really negatively impacting my workflow, which is an issue, as I'm a full-time animator.

Can you please re-post the links above, as it seems they no longer work, and advise on any other possible solutions for my files changing after I save and close them.

Lastly, I would just like to take a moment to say that since Adobe has started pumping out more frequent updates, I am having more problems than ever. I seriously wish they'd go back to the days of pushing out more meaningful upates 1-2x per year, instead of endlessly pushing out buggy patches that only result in headaches.

How do you reset your LR to previous.    I am encounter problems with brush stroke.    It is highlightening as if I were using correction.    You cannot correct nor adjust with the subject turning into a white blob.     

The brush tool was not set to normal.

Thanks very much!
