There's something really strange and buggy going on with CategoryTree updates.
Sometimes it does not want to update until I clear the cache in my browser, sometimes clearing the cache does not do anything.
Now I've stumbled upon another weird thing. I added a couple of pages in my custom namespace and they won't show up in the tree unless I log out. When I stay logged out the pages are there, but when I log in again they disappear.
Please, help me to solve this annoying problem.
