Closed-then-merged question missing “closed by” and “merged to” footers
We have had some crossposting between cs.SE and math.SE and solved the issue(s) by migrating to one site, closing one of them and merging it into the other.
Now the question list looks like this for me (moderator):
And the closed/migrated question:
There is no indication whatsoever that the closed question has been merged somewhere (and where it has been merged to). Not logged-in users (and non-mods resp. low-rep users, I assume) do not see the closed/merged question and are forwarded to the merge target when they try to visit the closed question.
Please label merged questions as such (maybe just like deleted ones?) and show the merge target.
