I noticed that, this happens when I set comment sort to Top. Works fine when set to Hot. Still in beta, they'll hopefully fix it.

Thanks, that makes it a little more clear. Seems like that might be something more than comments out of order, though. At least as far as I could tell the hierarchy of post times appears correct, it's just not showing everything.

Had that one as well. Makes reading posts with many comments almost impossible. Let's hope it gets fixed soon.
