- Combat logging protection not working
Currently many of our features such as queued loading, combat logging timeout, etc... have been disabled as there is the possibility that they will cause additional strain on the central server. Once we know that we can handle the load we will begin implementing these. We do expect this will be a long process, and we'll be working with the community to identify effective ways to deal with this."
