From Nathaera:
It seems they may have fixed those little bugs from the first two "test" connected realms.As a part of our ongoing Connected Realms implementation, we will be working toward connecting our next pair of realms, Black Dragonflight and Skullcrusher – we’ll provide another update once we’ve finalized the date. We will also update this thread with any additional information that becomes available. Please be aware that as a part of the process, realm times may change to align better with each other.
We are currently evaluating additional realm connections and plan to provide a more complete schedule at a future point in time.
