I have a simple addon of my own that just does a few movements / scalings of the standard UI and one of the things it does is move the player frame. More specifically on player entering world it runs the following:
Since patch 9.1.5 I’ve encountered an issue in Theater of Pain after first boss when being moved down (you enter a vehicle apparently called Trap Door Rift) and the same thing happens in Plaguefall if I get picked up by the tentacle mobs. What happens is that he frame moves to its default position in the top left corner.
Does anyone know a way to avoid this? If I run the exact same scenario with the above code disabled the issue does not occur, in fact it does not even show the intermediate step of being in a “vehicle”
