I noticed that sometimes when I respawn during PVP as a KDF player, my UI is suddenly Federation blue, including most icons. Some icons are still using the KDF red. When I leave the match, it goes back to normal red. So far, this has happened to me only during Arena matches ever since Season 6 came about. But I have not had the chance to see if it also happens on Cap & Hold matches, since PVP has barely occured since Season 6.
Posted this in the PVP zone as well. This has been around for at least a week prior to S6 launch (on tribble.) I don't see how they didn't fix it prior to launch as it only affects PVPers, not PVEers. Oh wait now I understand.
