I’ve been looking between some instances to see how they look to each other and I came across this post/comment.
As you can see the original comment was deleted by the creator, but is still intact on the off-instance copy. I had presumed that each instance would relay the change, whether be an edit or deleted by creator, but perhaps its either an Admin setting or there was no event to push the change.
Just found it interesting and wouldn’t mind understanding more about how it works.
I have noticed the inconsistencies between votes, comments, edits, etc,
I had thought they were decision based, but general bugs might just be it.
