Stockfish Analysis are sometimes very strange

I had some really good matches here on lichess. Watched replays and saw suggestons of stockfish in my games which are really not practicable. The questionmark if i played a knight genius-like between queen and king is not comprehensible, considering that I forced the moves of the opponent before in this situation. There was no faster mate given in that situation. Stockfish declared this as inaccuracy ?
Above this: suggestion of first move = Pawn C4 is in my opinion a joke. Lichess and Stockfish could do better !

Have no idea what you're going on about (unless you post an example).

Where's the game?
~ Share the link of the game you are referring to.
Also, c4 is the best move according to Stockfish. It can calculate at a particular depth. So, c4 can't be bad. That's just your opinion.
