Ah … right … yea I’ve seen that happen occasionally … I had actually presumed that something had been changed with that post, perhaps by an admin or something cleaning stuff up, and that triggered a new timestamp for the post.
Maybe still a bug. I’ll keep track now of when it happens as it might help sort it out.
But still, that’s rarely the case for me. Just went down a fair way in my feed now and there wasn’t a single occurrence of it. Could it be particular communities causing it, maybe from instances on older software?
Otherwise though, Hot seems to do what I’d want. Combine with a bit of New or Top for an appropriate time window and I’m all good.
For comments, Hot/New/Top all do what I’d want too.
