Xbox Legend achievement not unlocking

[AnguishA]

I have been playing the game off and on for a few weeks and decided to get all the achievements. I haven't had any problems with any of the except for the legend achievement. I have earned a total of 34 mil gold still no achievement. I even waited to sell 10 mil worth at once and still no achievement. Has anyone else had this issue? I see a ton of my friends have the achievement. Also I play on xbox.

Did you get a reply to this. I also have the same problem on Xbox currently. Up to 12mil on single save file and achievement not unlocking. Took 100 hours to get here
