Problem position using Scorpio Egbbs

[syzygy]

This turns out to be a feature than a bug in the new bitbases
Enpassant, like castling, is not accounted for during generation of the bitbases.

Not accounted for at all? Or are the ep positions themselves just not stored?

Yes I understand it, what I am actually trying to address (my mistake) is that of all the positions that I found, this is the first time that e.p capture is not possible after a 2-step pawn push.

Yes, now I see what you meant. Thanks Ferdinand, for your help pinning it down.
