I flagged my question to be migrated on stackoverflow as suggested by this answer.
The moderator told me that the question is too old to be moved and told me that they can just delete it and then i can post the question on the other site. Which I'm completely fine with.
What got me puzzled is that I received a negative votedown on my question after that event as shown on my reputation history. It does not however appear on the question.
I am just very curious why I see the behavior? Is this the price you have to pay for flagging your own post and getting mods attention (which I am completely fine with btw). Is this something i should expect in the future. Or is it because I have done something wrong? I don't think it is but could it be a bug?
Here is a screenshot:
What confuses me a little bit more is that moderator actually marked the flag as helpful so it doesn't seem like i should receive negative reputation. How bizarre.
