If you ever encounter save bar went missing when you try to edit the resources,
you will realise it only happen to weblink / symlink type of resources.
I realise this is due to the problem of tiny mce plugin, which in my case, might be obsolete due to some upgrading issue.
What you may do is keep uninstall and force-removal on tinymce plugin until you no longer see any version of it.
Then, in package manager, re-add the package again.
Hope it works for ya :)
