I'm getting the following error with the mod:

6x RWN_ArchDistance/DistanceIndicator.xml:4 Couldn't find frame parent: MainMenuBarArtFrame

Are you certain that it's from Arh? Because it seems like its coming from a different addon: https://addonswow.com/rwnarchdistance

Thanks for using Arh. It's better than that addon anyways ;)
