I have been working on a video all day. I've been saving it constantly as I have always been doing because I know it shuts down a lot.

Recently I made an edit (i trimmed a video clip i believe) that made some of my thumbnails disappear as i hovered over them. Though they are technically still there. I assumed it was just temporary and would be back to normal after i restarted so i saved and opened it again, but it was still the same, it has been for a while.

I inserted a pic. As you can see it still says "how many items are there at the bottom. I know they are a lot but I was in the process of getting rid of the unnecessary ones.

Also though they are technically still there, when i click "add videos" in that large white box, it takes me to my files instead of clicking on a video clip.

I really want my video back. What can I do?
