One more: I'm adding a new tag to a vnet and I'm receiving this error here:

~   └─ azure:network:VirtualNetwork  ssvc-vnet               **updating failed**     [diff: ~tags]; 1 error
 
Diagnostics:
  azure:network:VirtualNetwork (ssvc-vnet):
    error: 1 error occurred:

Anybody gotten that before?
