This is classic. 2 of the 4 new buildings (if not all 4) have what looks like an error in their gold payout/income (it looks like an extra zero or two was added). BUT, the way that buildings payouts have been increasing like crazy, I wouldn't put it past GREE to intentionally do this.
OR -
Did GREE intentionally issue them this way, so that when they ultimately correct them, they hope that some people will not request their gems back??
Your guess is as good as mine.
A&F, Sirius, GREE - are new _okstad's Dwarven Ore and Black Feather Tailoring building incomes wrong at level 1????
