Recently we had a Pokémon Go question asking for how a specific feature works as of a specific patch. We also have an old question which asks about how the feature works. I believe the answers on the old question were outdated when the new question was posted, however they have been since updated. So we now have two questions asking the same thing with the same answers and I don't 100% know how we decided to deal with these. Should we dupe the old to the new, the new to the old, or leave them be?
Honestly, this should never have been reopened. The duping process did exactly what it was supposed to. Answers got updated, helping the asker of the new question, and all was good.
This insistence on not duping questions because we don't have an up to date answer just causes more work for everybody. Reopening questions on that basis, even after answers have been updated, does us all a disservice. If asking a question causes us to update existing answers, the duplicate process is working as intended. Don't reopen a question if the original gets updated answers; now we just have two questions asking the same thing.
