So seems like my upgrade to https seems to have caused some issues with the comments section and some comments are missing. I'll try to fix it this weekend if I'm able to. Just wanted to post this here in case some people thought I deleted their comments!
Update: So it looks like the problem was on disqus' part, and my discussions from older posts are stuck in some sort of purgatory state and only viewable on my profile, but on the admin panel it doesn't even exist. Asked for help on the discussion board but I'm not holding my breath and may just have to come to terms with losing the comments I've had.
