When you update the owner of a post, it updates the timestamp for that topic.
This was an expected behavior that felt like a bug. If this is not a bug, I suggest we add an option to the change ownership modal dialog to leave the timestamp as-is.
Background
We imported a lot of historical conversations into our Discourse instance. Because of the platform we came from, that included a bunch of duplicate user accounts. As part of a general cleanup, we were de-duping those user accounts and changed ownership of posts. That pushed old topics up to the front page. We had to go back and re-adjust the timestamps for all these topics back to get them back in their expected chronological order.
@codinghorror this just keeps coming back over and over. Perhaps the default should be that owner,tag,category,title edits on OP for 1 post topics are always non bumping, configurable via site setting ?
It’s the same thing, postrevisor does the editing of owner, and same class of change, mod steps in to reorganize old content, same “bug” unexpected bump on topics
I guess this is a bit wider cause it can also be last post in topic
