This answer mentions that you "will need to keep restarting until it appears." because it is a "rare node". I have provided the Game Seed that you can enter, so you are not dependent on RNG. I feel this is quite helpful, because you don't have to restart over and over again, until it works.

Perhaps your edit to the answer adds context that the author did not intend to have, or it ruins the spirit of that answer. In this case, I would recommend creating your own answer to the question, and adding your details there. Your answer may not get accepted, but additional info in the form of a separate answer is not a bad thing.
nightsurfer's points are certainly true. I also think in this case, your edit made more sense as a comment on the answer rather than an edit. My reason for this is because of what nightsurfer said:
