I am having similar issues starting last night after updating the game and server. I am on a vanilla server with no cheats enabled and no plug-ins, so I cannot give exact coordinates, but using over world maps, I am VERY far away from my linked nether portals. One additional thing that I did have happen is that sometimes it sends me to the right portal, sometimes it doesn't. If it doesn't send me to the right place (nether portal), then the first time I arrive in the wrong nether area there is no portal. The most recent occurrence of this was approximately 10 minutes ago. I did eventually find 1 obsidian block in the ground (top layer), and when I stood on that it sent me back (like a portal) to the over world portal that I originally used. When I went back through the portal to test it further, I was sent to the correct linked portal and not the new area.
