EDIT: So turns out it was the wifi network I was on, found another few videos elsewhere hidden. Now I'm back home they're all there! Didn't know that was a thing, thanks for the responses though

Does anyone know why a bunch of lets play videos have seemingly been hidden from the YouTube channel? Was enjoying watching some of the old wheel of fortune ones, but now I can only see one of the videos in there. The rest in the playlist it says have been hidden.
