Alright, i'll keep looking at it. Did you notice this happening after anything in particular?

Also, once I can't seem to configure the size of the chat box with Move Any to fit hydraUI size, so it ends up being bigger than the HUI chat box. I can probably make the HUI chat box taller, but I prefer to have chat box be small to show more of my screen

Edit: Also, it looks like the Move Any chat box just completely overwrites the HUI chat box, so there's no more colored names or links available

One thing that will reliably reproduce it (it seems) is opening edit mode and closing edit mode (making no changes), which leads me to believe it's an issue with the edit mode changes from dragonflight.

What is happening is that when it desyncs, it is moving to where the blizzard chat frame is set, wherever it is on the screen.

The current workaround I am using is using MoveAny addon. It's just slightly complicated because I can't move the chat box with Move Any while HUI chat box is enabled, so I have to keep disabling it, guessing approximately where it lines up with move any, re-enable it, and repeat.
