I got this problem all of a sudden now.

The funny thing is that I can play for hours in the drenai starter zone, but once I enter the non-instanced part of the deadmines or the actual deadmines my four notebooks with the /following characters do keep disconnecting randomly. Sometimes one, sometimes two. It is really doing my head in.

I removed all add-ons, the only recent addition was automaton, but that did not make any difference.

On the bright side, the problem is fairly consistent, so I have a chance of troubleshooting it.
