Update Bug.

And I get a similar thing in sightings/nearby too.

If I go out and back into the dex it can fix itself...or be others that don't display properly.

It is happening a lot, and becomes a distraction from enjoying the game.

Ya, I already kind of mentioned this

For me, just closing the pokedex and reopening did nothing to help, but after closing and restarting the app a few times it cleared up. I just checked againand it is still working properly.

Something similar happens for me as well. And pikachu hats bugged, and avatar goes black, and app freezes all the time with black screen.
Most bugged update ever. And it's even funnier that last update was revoked, but niantic is fine with current one being so glitchy (facepalm)
