I found an old thread of mine asking the same question:
http://www.wowinterface.com/forums/s...ad.php?t=54172
... answered by many nice people. Semlar gave a working solution (4th post) to print out the map IDs used by wowdb/wowhead/others so the numbers I'm looking for were in the game once:
Code:
/script print(GetAreaMapInfo(GetCurrentMapAreaID()))
It's second return is / was the number that dataminer sites use. However, I can't get it to return anything in BfA beta. If this script could be "converted" to BfA-compatible maybe I can get the numbers?
