I transferred 100 million gold off my vendor, but the gold did not show up in my bank box. The gold is definitely not on my vendor either. I've troubleshooted this bug all morning. Another player told me this happened to them as well. Be careful to notice when this happens to you. Also be forewarned that there is no GM help for non-Japanese speaking players on the Asian shards including Hokuto. I got this response when I tried.
