I'm not sure if this is a Voyager issue or a Lemmy API one, but when viewing the profile of someone who comments but hasn't made a post in a while, old posts will be sprinkled randomly through their comments list.

Selecting Posts or Comments returns everything in the correct order; it's only the overview that's wrong.

On a related note, when viewing my own profile it suddenly skips a few weeks of comments after the first page:

(My apology for the politics, but that's where the split was)

This too only happens on the overview page and not when viewing comments alone.
