It actually isn't, that's a mod overriding the default game files. Try launching safe-mode, you'll see it's not vanilla. ot: repost
actually, if I remember correctly, I made a thread discussing agree and informative ratings sudden vanishing, and then we got agree back somehow lolmao OT:
I just found out that there were dislike, disagree, awesome, funny and useful buttons as well thanks to that thread. Interesting, but that´s just too much IMO. If I was in charge of deciding which buttons are going to be available, it would be like (can be used as awesome and funny), agree, dislike (can be used as disagree) and useful (can be used as informative)
