Unless I'm a complete idiot, pretty sure dxc3 is not allowed. Interestingly enough, if I push undo, the game allows me to take it! I don't know if it would have worked in game but I'm surprised to see a bug like this either way.
Engine recommends (and allows) illegal move?
Sort:
I opened an analysis board and played out this exact game, and it allows dxc3! I don't like thinking that I played such a bad chess game that I broke the engine haha.

It's a legal move called en passant.

No this is not en passant. There is no pawn next to the white pawn on d5, so it must be a glitch.

Assuming you are referring to the diagram of @agccc, there was a pawn on e5 before it was captured
*note it can be found on move 10... e5 as you can see in the screenshot on the bottom of their comment.

Yes, I was referring to that one. The other one is en passant.

Both are. @agccc captured the pawn with the bishop and analysis is showing that was a blunder and en passant was the best move,

My mind is completely blown, thanks for the help!
@Sadward in your game, your opponent just played c4 and you moved Qe6. The engine was telling you the best move was dxc3, which is en-passant (smth i always miss 
), and en passant is a legal move. As such if the engine recommends dxc3 the move AFTER you play Qe6, then it is illegal.
@agccc same thing. Your opponent just played e5, and you took the e5 pawn w/ ur bishop. The engine recommends taking en passant, which is legal. Again, if the engine were to recommend dxe6 AFTER you play Bxe5, then that would be illegal.
Heres the link for en passant that Martin posted in case you missed it: https://support.chess.com/article/683-what-is-en-passant
