When trying to move a folder and it’s contents to another folder, the move operation will complete, however, the content browser will not remove the original folders.
Also, when you attempt to delete a folder, if it has any sub folders, it will not delete, even if there is nothing in those sub-folders. You must first delete the sub folders before you can delete the main folder.
In fixing this bug, would it be possible to also look at moving / copying level maps too?
Thank you for submitting a bug report. While I was not able to reproduce the first part of the issue, I was able to reproduced the issue of not being able to delete a folder that contains (or contained) subfolders from the Content Browser and logged it as UE-38752 which you can track on the following link: Unreal Engine Issues. Please be aware that since the issue must be reviewed and prioritized by our development staff, it may be a while before it can be addressed.
Regarding the moving/copying level maps issue, please start a new post with clear repro steps in order for us to recreate the issue on our end.
