What steps will reproduce the problem?
1. Open MoveAnything and select the Class Specific Deathknight Rune Frame mover checkbox.
2. Drag or use the safe nudger to reposition and resize the Deathknight Rune Frame. I set mine to 1.2 resizing, and centered it on my screen below my character.
3. Save the settings and exit the editing mode. Now try to zone through a portal or zone, or enter and then exit combat with something. A LUA Error will appear.

What is the expected output? What do you see instead?
I expect no LUA errors when using a portal, zoning into a new zone, or upon exiting combat after having used MoveAnything to resize and reposition the Deathknight Rune Frame.

What version of the product are you using?
This error occurs in version "R: 16.0.3 for 7.0.3 Jul 23, 2016"

Do you have an error log of what happened?
I have two very similar but subtly different errors that I get from the default LUA error panel:

Message: Interface\FrameXML\RuneFrame.lua:102 Usage: UnitPowerMax("unit"[, type][, unmodified])

I posted a thread here (http://us.battle.net/forums/en/wow/topic/20747637309#post-1) hoping to figure out if it was something others were aware of and Blizzard was working on. However, after further testing by disabling MoveAnything and then zoning through portals or entering and leaving combat, no LUA errors were reported. This let me conclude that the source of the error has something to do with MoveAnything and the modifications I listed above. Resetting the frame via the reset button, reloading, and repositioning the frame how I liked it resulted in the same behavior.

This section is the MA profile I am using my my Death Knight.
