This might have been an issue in an earlier version, I haven't checked this for a long time.

If I go to my saved/bookmarked stuff, I can see saved posts just fine but going to the comments tab it show no content.

If I log in to another client or the website, it is all there though, so just an issue displaying that.

I am on piefed server, so maybe something to do with a Piefed update? Just a hunch.
