Flare bug on Sandtrap & Trait Zones question.

I’ve had issues on Sandtrap where the entire screen is covered in a glare similar to the Flare equipment, but only for one person in the game. It has happened to at least one player in my local games any time we get on that map, and can last anywhere from a second to several minutes. It also resets on death, isn’t location specific, and only blinds one person. If this isn’t the right place for this bug report, please redirect me to where it should go.

Also, in Halo 4 forge, how do we edit Trait Zones now? I don’t see an option in game, and the pause menu, where the option used to be, is just a generic MCC pause menu, with no game-specific options.
