Have turned off all addons and nothing changes. Not sure what has happened since yesterday but this is really strange. It is especially off-putting questing in normally dark zones and being reminded every time I have to speak to an NPC what it 'should' look like. CWC tonight was very shiny and I could barely see the quest NPCs when speaking with them. Any ideas...?
