We are currently working on fixing a few minor issues to some of the new quests in Dragon's Spine and we are also looking into some other points like Excavation Guards attacking players when they should not and similar issues. Most of these fixes are ready internally and we will have to see if the update will be ready for the live servers next week. This depends of course also on the results of the internal testing.

We are also aware of the user interface language elements of Russian and Polish clients that have disappeared with Update 4.0. We are working to correct this as well as soon as possible.
