Well... That does seem to affect it. This character (Crimson Cop) is the shortest that the selections will allow. I used up several free Icon session tokens so I could experiment. It looks like any height setting affects the placement of this. I setup 5 of my 7 costume slots with progressively taller character heights and each one affects the placement differently. I also checked another character (Second Sound) that is the shortest the system will allow, and she gets the same placement as I showed in the previously attached screenshot. Further, all of my other characters are the default height (a little over 6 feet) or a bit taller. The default height seems to place the info where it has always been.
I know that it was not present before. Crimson Cop was my second character in Homecoming, and he's been around for over 2 years. (Although, I favored other alts for a while, so he's still only level 46.) I don't always use the info when I'm on a team and things are happening very rapidly and chaotically, but it is a necessary thing for me when I'm soloing (especially with blasters). "Out of Range" and "Target Blocked" mean that I need to adjust in a different way, so I pay attention to those things. Therefore, this has to be a somewhat recent (maybe over the last few months) change in the operation of the game.
Am I the only one getting this issue? Do other people's Combat Warnings (for lack of a better name to call that info) move with the height of their character? Is my human memory crap, and this has always been how it works? Or is this a recent bug? If it's not happening on other people's game, then maybe I just need to uninstall (and clear any leftover files) and then reinstall the game.
