I recently came across an issue where I had to remove a Template and add it again because I was getting an error if I tried to edit the settings of it when it was converted back to a VM, the only fix I have found for this has been to remove the VM from the inventory and re-add it via the datastore browser.
As I haven’t had to do this much (in fact this was the first time I did have to do this) I haven’t come across the particular issue where when I tried to re-add the VM back in to vCenter I tried browsing to my datastore and discovered it was blank.
