I have a sunset sequence in which I made a half dozen exposure changes to compensate for the darkening conditions. LRTL shows the characteristic sawtooth blue line as Gunther shows in his tutorial. I set keyframes before and after the jump as he suggests, and save out the metadata.

My problem is that when I reload the metadata in Lightroom 4, Lightroom is not seeing the intermediate starred frames -- it only sees a star on the first and last frame.

Any thoughts on what I might be doing wrong, or is this possibly a glitch with LR4?

Hi, I double checked everything and keyframe transport from LRT to LR4 and vice versa works like a charm.
So please make sure you followed the new workflow (see lrtimelapse.com / section workflow and my new tutorial video!) Do it like I show it in the video.
Make sure you have set your LRTimelapse to the LR4-mode (settings, restart) before beginning.

Please keep me posted!
