No one can tell me if it should be "Balkanabat" with a "t" or "Balkanabad" with a "d". I have seen it both ways online, on maps, and even at work, where depending on the business system being used, the spelling is different.
Edit: The "d" or "t" issue is a common one. There are many names that could end with either letter including the given names of many people. I've seen plenty of people with names spelled both ways.
