In order to indentify the issue, we require more information. If this was a wide spread issue and if it was an issue on our end, we would fix it and apply emergency patches if need be. However, since this issue seems relatively isolated, there has to be a cause that is triggering this problem. However, as you haven't provided any substantial information, we are unable to further assist.
Account sharing is against the Rules, no one other than yourself should know the ID and PW of your account. A GM or any other member of staff will NEVER request such information from you. If you have shared your account and someone is logging in at the same time, this will cause a forced disconnection.
Again, I'm not suggesting that is the cause of the problem. The problem us currently unknown and since the issue isn't widespread, we cannot provide further assistance until we know precisely what we're looking at. Disconnections can happen for a variety of reasons.
What other information do you need from me to fix this issue!? Also I have never given anyone my information or anything ever I am just saying if you logged in on your computer on me it would give you this same bug I and BlueFox7580 is getting. Can we roll back the patch that was done on wed? and see if that fixes the problem?
