Friendlist sometimes doesn't show "Show more friends" button

When you have a pretty extensive friend list, you need to click the "Show more friends" button multiple times to get to a particular account, as they are alphabetically ordered (most of the time, sometimes it just isn't for some reason). Sometimes this button just disappeared, I was removing a bunch of people from my friend list and suddenly the button just disappeared and now I can't click it more than a couple times, even though I know for a fact that I have more friends in the list than it is showing me.

Another, less broken and more annoying bug is that every time you perform any API operation on a friend card in your friend list, the whole page refreshes, and you have to click the "Show more friends" button multiple times to get to the same point in your friends list where you were. This is especially annoying when you're trying to clean out 100+ accounts from your friend list. (lol)
