So I just got back into the game after a long absence, and I'm working on High Isle. But a lot of Amenos is missing. All the area around the Flooded Coast wayshrine is simply not there. If I get too close I fall through the world forever. And while there is land where the Shipwreck Shoals delve is supposed to be, there's nothing there. I've watched other players disappear there, so I know where the door is supposed to be, but I just see bare ground. Logging out or quitting doesn't help. The problem is persistent. Anyone got any ideas?
