I caused a bug: the X saw the S and @ at the same time. It went for the S and I couldn't direct @ any more, who ran to a corner after getting scared from the X, who for some reason stopped being able to see @. I had to hit Esc to restart manually (and I also never figured out how to get it to go for the S and had to skip this one, lol): https://imgur.com/a/66syeHm
