Over the last couple of weeks, I have noticed an increaded time delay in what would show up for member location and/or rep status on my machine.
This week, during guild missions, it showed everyone at our meetup location during the entire length of guild missions, even when they were right next to me, in my party, and on my instance of a map. It also showed some of them as not repping, when they clearly were, talking in guild chat, and I had visual on them repping.
