Can confirm that unfortunately it does. If you're a lv20 killing lv20 mobs and you invite a lv5, your exp crashes or outright vanishes.

It's a pain when you join a NM group hoping to get a little challenge log exp along the way but the one low level is killing the exp. You get punished for refusing to kick them.
