Stalkers!
Good news: we have finally found the cause of FPS problems and we are currently working to eliminate it.
However, the problem is quite a large-scale one, so the solution will take some time. We cannot tell you the exact time of completion because, as it is, we do not know it ourselves. But we want you to know this is our top priority and we are working on it.
After we solve the problem, we will do our best to make it worth your while - a compensation will be in order.
Also, we changed the procedure of characters transfer between servers. Please contact Tech Support for detail.
