Actual this Bug or Problem exist, since the last Alpha Build (the Version after 6994).
After logging in, depending on the Sim I'm in, the Message in Picture 1 appear after some Seconds or some Minutes (at one Sim I was there Hours without the Message).
After the Message appear, I can't longer move or change something (like this old Times, where SL has log you out, but without kicking you from the Viewer).
For other I'm still online.
After a Friend has send me a Teleport (I have get it and could accept it), I was in an Area with negative Coordinates (Picture 2).
To prevent this Problem, I was using the Version 6994 for some Time.
Since Weekend, the Viewer is not longer loading my Avatar and I and other stay a Cloud, while I'm bombarded with "could not load Asset with the Name ..." Messages.
So actual, both Versions of the Viewer are not useable
