Update before 8.1 made an app disappear from start screen. Anyone else?

So the update before the 8.1 update took ages to install; but when it was finally done, I was missing a tile. I have no idea what it was and I, unfortunately, didn't take screenshots because I thought this update was just under the hood stuff for 8.1 prep. Anyone else experience this or know what app this might be? Thanks!

Xbox music tile is gone. Ita now called music. All my pinned albums left too. Thankfully habit reminds me what they all were. Maybe it was an app renamed

Not just that, another app disappeared. I had this app lower down in my lock screen. No idea what it was.
