When I finally got into Dawnbreaker tonight (after a long attempt trying) the castles were all transparent and I could run straight through them - yes really. Floating npcs standing in empty castles in the air ;P
All the castles showed as AD but I couldnt transport to them. That wasnt so bad but when I died to enemy fire I couldnt rez - at any of my home locations. I'll try and get screenshots if it happens again but I had enough and logged before I thought of it.
