I just found that this question had been merged with another, and I had two similar answers on it. I've now deleted the extra answer, but it's probably been that way a while.
Edited (because of George's great answer): Could we have a notification in the response envelope/recent activity for all...
I only once realised an answer I'd written had been merged to another post when I lost 5 points (because my answer got auto-unaccepted but also got an upvote) and investigated it. At the time I didn't even know questions could be merged. No idea if this has happened to any other of my posts!
@Zanna If you have thoughts about the feature request that haven't been posted there, perhaps you could post an answer, in which you could also include a link to that SEDE query (and to the MSE question?).
Hmm, why did I get +1 rep when that answer, which I had downvoted some time ago, was deleted due to the question it was answering being deleted? I thought we only got rep back for downvotes when the post itself is directly deleted.
