Okay, so everyone’s freaking out about the replies not working, so here’s a little how-to(-ish).
I’m guessing you have stylish. If not, go download it for chrome: https://chrome.google.com/webstore/detail/stylish/fjnbnpbmkenffdnngjfgmeleoegfcffe
Then, go here: http://userstyles.org/styles/80035/reply-fix
Click “Install with stylish.”
Also, I’m guessing you have missing e, so go to social features, and make sure that you have reply replies on.
Then when you click on the notes on a post, a reply should show this (using acciocaptainjackharkness as an example):
Click it, and it should take you to this:
There you go. You’re welcome.
Reblogging for those who have problems with the reply to replies functionality. I use it too, so this fix was really useful.
