Screenshots are all gone from my folder

OK so yesterday I was playing and all my screenshots were ok. I know for sure because I was taking screenshots for my family tree and my photo story. Today I was updating my family tree pictures and realized that ALL my screenshots but the new ones from CAS were gone! They are all gone without a trace, I checked my recycle bin but apart from the screenshots i was deleting yesterday there were none to be found. I'm clueless as of now. I know I've taken quite a few (really a lot) and not yet emptied the folder, so is there a possibility that the folder gets deleted after a while? I know that yesterday I tried the new Get to together feature of trying to have a look at my screenshots in game and that they were all in complete disorder, but I have not tried to make one a memory because of the disorder. I do have a backup of my Folders but from quite a while ago so not everything is lost but all my recent legacy progression is gone.

Does anyone have an idea?
