hi, i m having the same problem too, it only happen to my production server, which quite heavy load.
when i m create the folder, it appeared in the tree view, then after few mins, i switch to other pages then back to file manager, it disappered.
but my physical folder still there. very weird.
i went to folder and file tables, all entry removed. I knew DNN will auto remove when it detect the physical file is missing, but the file still in hard disk :(
is it because of the multi-thrend problem?
