This question already has an answer here:
I provided the fifth vote to close this question as off topic because it belongs on http://physics.stackexchange.com. From previous cases, I was expecting this to cause the question to be migrated to the physics site. Instead, the “put on hold as off-topic” notification was placed on the question. I then searched for and found the question on the physics site; apparently the author had cross-posted it there shortly before without notifying us. I understand that it makes no sense to “migrate” the question to the physics site if it's already there; but the note saying it was put on hold seems unnecessarily wrong – especially considering that it contains the encouragement “If this question can be reworded to fit the rules in the help center, please edit the question.”, which is inappropriate in this case.
(Note that this is not a duplicate of this feature request – the problem was not that my reason to vote to close differed from others'; all five close votes where for the same reason that the question belongs on the physics site.)
