I found this tonight.

Here s an excerptIf you’re overflying the Tirana FIR tonight, the Air Traffic Controller in whose hands the safety of your flight rests will be one of these three: a
Turkish controller, who has just been drafted in and who has never seen the airspace before; or an
Albanian controller who has been forced to work under huge duress, while colleagues remain in prison.
And if you think there will be a NOTAM to tell you about any of this, you’re mistaken. Albania does not want you to know.
