Do you happen to know whether Amazon offers older KindleGen versions for download hidden on their server somewhere?
We've been experimenting with this here, as well. It's our opinion that it's a K3 rendering engine issue. When we dl your test file, the "go to" on my Fire works. Of course, unfortunately, there wasn't really another page in front of it, as a viable test. It doesn't seem to work correctly on the K3. ETA: I mean to say, I do not believe it is a KG or KP issue.
We have several books we've tested--they work fine on KP, on Fire and on K2, but the K3 can sometimes--not always--jump to the middle of the first page of Chapter 1 (or whatever page is set as the "text" location).
I hope that this helps. (I would have replied sooner, but getting sideloaded files to finally SHOW UP on the Fire is a never-ending problem. It's very annoying. And, yes, I reboot and reboot, but for some reason, the delay time is frustrating as hell. Doesn't matter if I use wifi or USB.)
