Hi! I am currently getting lua errors when I attempt to enable aggro indicators on either the raid frames or main tank frame. it happens whether I select highlight on aggro or use the aggro square.

Swatter gives me this error:

Upon relaunching the game I am greeted with the error on login as well as this mess. (luna frames are unlocked)

When I attempt to open the settings window for luna I am greeted with this error:

If I delete the saved config in my savedvariables folder it gets rid of the error and allows me to setup luna with a new configuration however the moment i select aggro indicator in anyway the error comes back and breaks the configuration file.

I disabled all other addons to make sure it wasn't a conflict with another addon

Upon messing around with different settings and enabling and disabling different parts of the unit frames I have so far narrowed it down at least partially to the maintank frames. It seems like as soon as I enable maintank frames and unlock the frames to move it around everything goes out of wack

If I make sure maintank frames are disabled before unlocking the frames it doesn't seem to throw the error at me

Perhaps I have done something wrong but I made this change in the movers.lua file on my installation to see if it fixed the issue for me and I am still getting similar errors and broken frames that require a /reload to correct

Here are some clips demonstrating the issue

This behavior is the same before and after making the change in movers.lua. I think this issue should be reopened.

I hate to be annoying like this but I am still getting an error referencing squares.lua

I am no longer getting the highlight.lua errors so that does seem to be fixed. I am trying to look through squares.lua to see if I can identify a way to fix it, but i don't know my way around the code in this like you do 😄

inserting the line:

if not UnitExists(frame.unit) then return end

at line 170 in squares.lua fixed the error for me

Edit: Actually after looking through the code in the repo it appears the most up to date version would have the line being inserted at line 200
