it's because of a problem with our modified clients. If you are using a foreign client, you must do this:
1. exit the game from your foriegn client.
2. log in with the chinese client
here is where i'm not sure if you have to do it or not. i haven't tested...
3. enter the world
4. log out using the chinese client.
by not sure, i mean that maybe just being at the character screen is enough to tell the server that you're not in the game anymore, but i don't know. i also had the problem when i first started of my money going out the window, but this definitely fixed that. The english client will not log you out of the game. If you log out with it, the server will think that you are still playing as you sleep.
