When the app freezes in the middle of an encounter and the pokémon is both caught and not caught.
Otherwise known as EVERY FUCKING TIME
When this happens: wait for the white pokeball to appear it the corner once, disappear, appear a SECOND TIME (this is the game saving your catch), and disappear once again. When you reload the app, you will have that Pokemon.
Wait…for real? I’ve noticed that sometimes it saves them and sometimes it doesn’t….WAS IT MY FAULT ALL ALONG?!
