I was reviewing this short answer to a question about Minecraft Story Mode. The question is about regenerating hearts, and the answerer discusses the hunger mechanics. However, I believe answerer thinks the question is about Minecraft. I haven't played Minecraft Story Mode, so I have no idea about the validity of the answer. I fixed the grammar as part of the review and moved on.
However, I'm wondering if this should be flagged as not an answer. Looking at this meta answer for Flagging “answers” that answer a completely different question, I would think that it should be flagged since it doesn't actually answer the question. However, looking at this answer on the Stack Overflow Meta: When to flag an answer as “it is not an answer”?, I would think that it should be left alone, but downvoted since it could be a related answer.
