It took a while, but I caught it with the debug version (though I don't know how much it will tell you). Here's the sequence:
John: Loved, stuck
Sussudio: Banned, stuck
Sexy Chick: Banned, stuck
Jesus Gave Me Water: Banned, lost (didn't see when)
One Foundation: Banned, lost as soon as I loved the next track
Too Late, Too Late: Loved, stuck
For what it's worth, I also deleted Sussidio and Sexy Chick somewhere in the midst of it. That's what I'm using Ban for, to mark tracks for deletion.
And the error log:

For good measure, here's a screenshot of the Now Playing List. You can see how the "skip track" sign is still there, but not the ban sign. Also, I checked and the "exclude from playback" field is unchecked.
