[solved] Ask HN: Is HN silently deleting/blocking too long comments?

Wrt. the recent article about DST I posted a comment with two links to useful (but sadly German) youtube videos as well as something between a subscript/summery of this videos.

Only to notice that this comment never appears at all, it organically was there for a moment and then it was permanent gone and any try to post is just silently does nothing...

Well the comment was pretty long, so I guess HN might silently remove to long comments to prevent spam or similar?

EDIT: The solution was I'm stupid and there is a easy to overlook More button at the bottom of the page. Supper embarrassing. Thanks for the answers.
