I had that happen as well, suggesting the same move I played
Free Analysis Fail
If you want automatic analysis, download scid (free) and your favourite engine (stockfish is very good and free). Then use the annotate feature.

I APOLOGIZE. I posted the item below supporting your position, but I am not a free member. I am a GOLD member and the anylizes still is comical to me and it makes funny blunder itself.

I only have submitted two games and all the time the comp suggests a move that was silly to make.
Like in your game it suggested Black should have taken the Rook with his Queen. I also would have chosen not to lose the queen without compensation.
In one of mine I sacrifice a bishop on the h5 to break up the pawns in front of the King. It said it was a blunder. Heck, I attacked the kings position and I put a six move mate in "the conditional feature." But the computer showed other ways that weren't a mate and suggested that the game could have continued.
I will try several more games but just as a COMICAL feature.

So...I understand that the free analysis is not quite as good as the Premium Member analysis, but the last game it analyzed is kinda...well...Just take a look at move 7. I played Nc3, but Nc3 is OBVIOUSLY better than Nc3, if you get what I mean. >.>
