Computer Analysis Errors

Has anyone encountered analysis errors? I notice this more often when trying to analyze games played vs the computer. At the end of the game, I'll run an analysis and the report doesn't even show the correct moves made or it'll suggest a move that is impossible to make. Like I said, this happens to me more often when I check games vs the computer however it does happen when analyzing games vs players, on occasion.

For instance, in one of my most recent games (see image below) I made the move Qd6. The analysis highlights my move and reports "Inaccuracy for move 31 Qd6, a better move was Rc8." But I can't possibly make that move. My rook is stuck on f5 and unless it becomes a bishop, there's no way to make the move Rc8.
