I dont know if this kind of information is worth any Buck but its 100% true.
I dont know how anyone can give a Yay or Nay to it since i was the only one talking to the GM.
This GM showed us the GM City (see General forums for pics).
When asked about the hotfix he said it was to "fix a gold dupe with housing plots".
THIS WAS ON TEST SERVER
So get all your gold out now, before its fixed.
