I can only confirm I have had the same issue for a while. For me it is mostly when I press shift-tab. regular tab works fine for cycling.
The problem seems to arise from the point moving to the beginning of the buffer when outline-back-to-heading is called, which raises that error. I don't have time today to dig much further. I hope that helps get a solution though! I miss outshine!
