Bug report, en passant not possible

Hi, i just played this game:

After 25. b4 i was not able to do en passant.

Thanks for the detailed bug report; unfortunately, the FIDE rule works somewhat differently since "en passant" means "in passing" and refers to the b3 square, not b2:

Wow, a new twist on the en passant fun. Nothing is wrong here. That's not where en passant applies. I kindly suggest taking a closer look at the rules.

I stand corrected, and more informed. Thanks!
