8/8/8/1B6/6p1/8/4KPpp/3N2kr w - - bm Kd3 Ke3; c0 "CCC post by Tim Foden, id MES.831, white wins, 1. Kd3 g3 2. f4 Kf1 3. Kd2+ Kg1 4. Bd7 Kf1 5. Bh3 Rg1 6. Bg4 Rh1 7. Be2+ Kg1 8. Nc3 Kf2 9. Ne4+ Kg1 10. Ng5 Kf2 11. Nh3#"; id "ZPTS.21";
I think the position 21 with Ke3 as second bm is wrong.

And at the same time I found a bug with Gull and promotion
Gull sees mate with Ke3 and Nc3 because of this.
I think it affects all versions.
