We are still working on the issues that have been causing massive lag and other server issues since this weekend.
Here's what you can do to help:
Have you experienced either of the following since the patch?
* Being in a dungeon and suddenly running into an spot where your 3D area went completely black
* Players being invisible and not able to interact with monsters
If so please reply in this thread with the details and most specifically, EXACTLY WHEN this occured.
