Edits ruining posts times and order?

A few minutes ago, I edited a not very recent message of mine that hadn't received a direct answer. To my surprise, the original date and time of posting of my message were changed to those of edition, leading to the absurd that all subsequent messages became older than my edited post, as this remained in its place. What's more, until a new message was posted in that thread, my edited post became the "Last post" for the software, appearing as such in the list of topics. And I was taken to it, not to the last post, if I clicked on the "time of posting" shown in the list, or the Last Post button at the top of any page of the thread.

In my opinion, not a very clever or useful new feature.

And I was kicked out of the forums when I was finishing writing this message
