A few days ago I logged into my alt to collect the daily reward. After collecting it my gold went the opposite direction. Instead of having 160k gold, it decided to go to -160k. I refreshed the page and that didn't help. I thought maybe i could fix it by just adding gold but it won't let me give nor receive gold. The following day I tried to buy and item from myself thinking that maybe it was just a misplaced negative sign and thought "no big deal". But apparently I had insufficient funds. When i collected 1k from the side mission, my gold went from -160k to -159k (that gold is only a rounded estimate to show the problem) i collected a few times and its did the same thing. So now i have come to report the problem, and created a video as evidence.
