WowAce

What steps will reproduce the problem?
1. Putting the addon folder in the Interface folder, and simply
2. Running the game with the addon running
3. Upon the initial loading of the new 5.4 version on WoW, after a few moments delay, the normal (without yellow circle) mini-map suddenly has a large yellow circle displays encompassing most of the mini-map, which almost looks as if a radius of some kind (not the tiny circles which show node spawn locations)
4. It seems as though when in different locations the circle changes it's size - I've included some screenshots to show this.

What is the expected output? What do you see instead?
To not have this large yellow "radius" circle in the mini-map - i can't seem to find an option to turn it off, and I've never seen it before i my years of using this fantastic addon.

What version of the product are you using?
1.27
