Flight Masters not respawning

What is happening with flight masters on Lordaeron today? Some of them have been missing for hours, not sure if they have been spawning back at all.

There's a slight chance that the Flight Master may have not been dead and all, but was kited off their spot to the point of unusability

I think there was also a post about missing Flight Master

Try google the respective FM's name and do some /target (insert NPC name here)

I found the lakeshire flightmaster on a hill south of lakeshire, can not be used.

The darkshire flightmaster has been gone for most of the day and I dunno where he is

Ratchet one is in the building texture.

stormwind flightmaster is bugged now too, hes down on a ledge slightly ahead of where he should be

This needs to be fixed ASAP, can't play anymore because FMs go missing EVERYWHERE atm. On 2 chars I'm now basically stuck.

SW, WEstfall, Lakeshire, Theramore, Darkshire and many others are just gone.
