Commenting more than 3x deep?

I noticed on chapters, that after the 3rd comment (reply), that the 'reply' dropdown is blank. It makes it hard to have a conversation, as the order of comments seem to change after other comments are made on the last comment that can be 'replied' to.

Keeps quote pyramids to a minimum.

Ya, that was my guess, but I feel like you can still cap the display at 3x, but still allow the reply on the posts (and display in correct order).

I tried to reply to someone in a comment, but my reply appeared before their response, even though I replied a day after they did. Too confusing be useful :(

Or, could the comments at least be sorted chronologically in ascending order?
