The zone gives us fatigue as soon as we zone in and even after sprinting in as far as i could, the fatigue did not go away.

Yeah, Throne of the Tides is NOT ready for testing.

There was a bug that would crash you if you entered Throne of the Tides that we saw locally, and it might of made it into this particular Alpha build.

The solution is actually to set all your graphical settings to HIGH. If you have one of the settings (probably water, but I'm not sure) at low, you could crash.
