Thanks for the reply. No, it’s something I’ve only noticed here and there. It happened to my reply to a post just yesterday and I can’t figure out how, because 1) I’d quoted the whole incorrect post, and thus had almost certainly used the speech bubble button, but 2) it was clear from the little “replied to” avatar on the upper right that I’d replied to the correct post, which was the one immediately following/below the incorrect one, now that I think about it.
Pure speculation but on the same forums I’ve sometimes noticed a reply appearing to precede the post it’s replying to (and other users report seeing the same thing), so perhaps it’s related to that?
