When you find problems like this, if you link Bryan in with an @ he'll have a look.
@Bryan isnt that right.
While your rooting about the @link in isn't auto completing properly. Shows the person but doesn't transpose it to the text.
It seems to be when I hit the reply button but I just tried 'Liking' a post and it did the same!Working fine for me, if it happens again make sure you're not viewing a cached page by pressing CTRL+F5 then try again.
