What steps will reproduce the problem?
1. Go to the Western Plaguelands Zone, and have the digsites below available
2.Visit Northridge Lumber Camp dig site, go to southwest corner
3.Visit Felstone Field digsite, go to western edge

What is the expected output? What do you see instead?

Archaeology helper HUD should be available throughout the zone. However, in the locations above, the boundaries are slightly too small, and the addon cannot be used for some of the outlying artifacts, or even when surveying along the edge of the zone.

Especially for the Felstone Field site, there seems to be some kind of glitch towards the southwest corner, where the HUD elements suddenly disappear, and you have to move and manually bring it back up.
