So after I updated to the new preview build, my Live Tiles have been acting weird. Like, if I try to pin a new one to the Start menu, nothing visible happens. But if I right-click the same app, it says "Unpin" instead, as if it was pinned after all. And when I restart the computer, the tile appears like it should have. Does anyone else have this problem? It's made rebuilding my Start screen really annoying, considering I have to restart again and again for them to even appear.
