Ok, I am using the clone stamp to get rid of something in my clip that I don't want there. I have done this 5 times already!!! No tutorials I have watched explain this to me. So I went thru every frame and got rid of everything I wanted, and saved my project. When I reopened it, the clones stamps I made are simply gone! They appear in the timeline, but are NO WHERE IN my clip and I have adjusted every knob in the drop down I saw and still nothing. WTF is this?! these bugs are getting ridiculous!!! HELP ME! There was even a point when I didn't close my project and stepped away, and then they were just gone!
Are you looking at the layer panel or the composition panel when they disappear?
What exact version number of AE are you using (down to the last decimal)?
Could you take some screenshots of your workspace while you're working and then do it again when they disappear? I think this will be the best way for us to see what's going on.
