I recently came across this question which immediately starts off with [sic]
I asked a similiar question 10 minutes ago, but pasted the wrong code snippet. I'm really sorry about that.
Going through that user's profile page, I found the original question which has been edited to remove all content of the question.
The user appears to have made a mistake in asking a question and received several answers that are valid per that mistake. The user created a new question because an edit would invalidate those answers. In a comment on the new question, the user stated [sic]
Changing the question in place would have changed the context and correct answers would possibly downvoted.
And kudos for thinking ahead to that. I do believe, however, that the user's response to this (removing content from the original question) was not in the best interest of the site.
What should be done in this situation? When a question asked incorrectly (incorrect being not what the asker intended) receives correct/valid answers, what should the asker do? I would expect the user to leave the question as is and ask a separate question, but my concern is that given that it's not the question they intended to ask, they may not be the best authority for selecting an answer in the initial question.
