You can watch a video demonstrating the problem
here. In the video, I will tag the sole "Eero" object with a bit of metadata saying "This is the only instance of Eero." I will then create one link pointing at "Instance #1" and another link pointing at "Instance #2" in the same text; clicking on either link takes me to the same object tagged as "This is the only instance of Eero."
rob, if you guys want my database to see what's going on, let me know how I'm supposed to send it over to you.
