PSA: don't distract yourself with your phone while in the Evo screen

Wanted to do a chain evo on Ugarte, as I missed his showdown earlier in the game. Got the first couple in and while looking up another player's evo path I sonehow managed to put a completely random dude in the new octpus evo. I have no idea how I managed it, no memory of hilding down X but somehow I screwed myself out of a good player.
