I recently noticed this. In the OG Lemmy web client, if someone replies to a comment that was deleted, that reply will show.
Voyager will nuke everything below a deleted comment. The entire thread is hidden from the user.
Is this a bug or something that simply hasn’t been implemented yet?
lemmy-ui has same issue. This is resolved in lemmy 0.19 but lemmy.world is still on v0.18 with bugs that have been solved. If its annoying you I recommend switching to an instance running 0.19.
