So... this has happened a few times now.
When I took a flight path from Dalaran to Coldarra, I ended up in Amber Ledge. Bit odd, but I didn't see what happened as I was tabbed out. However, just now, I fly from Acherus to Thorium Point. When I land at Thorium Point, I'm speedily forced through three loading screens and end up in... Loch Modan.
What the hell is going on, and how do I stop this?
