Can someone explain why comments are “disappearing”?

I don’t want to jump to any conclusions about censorship on posts relating to the LA fires, but all comments under this post seem to have “disappeared” for me. Please check it out for yourself https://www.reddit.com/r/conspiracy/comments/1hzc3wm/arson_is_a_weird_way_to_say_climate_change/
And if there is a logical and reasonable explanation for this please let me know.
