In the last two patch, 116014,116053 of the dev branch, if the server is dedicated or you are on somebody else local host, the GameMaster will lag a lot. Currently the only way the GameMaster role doesn't lag is if you are a local host and you are the Zeus GameMaster. This wasn't the case before those two patch. In the patch 115999 on the other hand, if a GameMaster was a "player" character (as oppose to a logical entity), everybody would end up having a weird lag. So the last 3 patch made it hard to play Zeus.
