iphone app analysis board bug

hello,

first of all amazing job on the site and the app! i just noticed something today and thought you guys / gals at chess.com should know. i'm attaching the game in question. i am playing black, and on move 12 i took his a-pawn en passant to free some space for my knight (besides the point i guess!!). using the analysis board on the iphone app (current version) after white's 12th move, the en-passant capture was not allowed. not sure if this is a general case (en-passant would be annoying to code for given that the analysis board is an instance of the current position with no past) or if it is edge-of-the-board specific or some other sort of limiting case. anyways just thought you guys should know so you can make chess.com even better.

cheers,
