Whenever I manage to finish an extreme one, I do it over and over again. This week I was successful.

Although I have checked my logical steps several times, I keep running into contradictions. However I cannot imagine that hepa has published an invalid puzzle. Perhaps someone could take a look and see if they can spot any errors in my solution path: ibb.co/N6S5kSzb

Nachdem ich für E 4-6 die falsche Möglichkeit ausgeschlossen hatte, ging es recht zügig.

 Actually, the 4-wing on that digit is enough.

 @ Oldies125: Thank you for the hint. I was working in the same line, but had given up. - Now it's almost easy. Thanks.

 No chain needed, pure base BX logic, 20 mins. A nice one.

 @Setti: How did you continue at 17 solved cells (e.g. decide hi/lo in col A) without any chain? A hint would be nice.

I also got stuck at 17 solved, though I feel certain I am missing an elimination using the X and B
