Thanks for getting #40652 in! I’m now on 2f2676180 with #40652 in the tree, did a full ./launcher rebuild app, and checked in incognito, so it’s not a cache thing. The carry-over is still happening though.
How it repros for me (sort set to oldest first): the first branch and the 2 replies under it always follow into the next topic and show up under the first branch there, as long as I move between topics without reloading. A full page reload clears it.
Unrelated idea, not a bug: when someone replies to their own post, maybe don’t add another nesting level for it and just put it below at the same level. Some apps do it that way and it keeps threads from getting too deep. Just a thought.
