Noble Dojorn Timers

[Frytard]

Interesting situation happened - Before we killed Noble - the OOA was in the middle of a rangers tracking list. After the Noble died, OOA went on top of the Rangers Track list and Only one Overseer of Air is up, we are not sure of the mechanic at this point but isn't killing the noble suppose to spawn a OOA everytime? Some of our members recalled a second overseer of air would spawn which would have their own Noble Djorn spawn cycle. Was there a patch for that?

Edit: to be clear Noble Popped while we were in sky. OOA was up before we were up in sky.
