It seems lemm.ee is missing data that is available in other instances like lemmy.world. Even posts and comments made on lemm.ee itself.

For example, compare the profiles of @sunaurus@lemm.ee on both sites. You’ll notice that on lemmy.world there are more comments more recently.

Edit: as soon as I posted this the data seems to have synced back up again.
