My sketchbook disappeared!

Hey mods! I just logged in to post some art and I can't find my sketchbook. It's not in my posts and I can't find it via search. What happened? Is there any way to get it back? I don't think I ever posted something to be disapproved of.
I have been posting there for quite some time now, I hope I can retrieve 20 pages of artwork ;w;
