This is an odd question, but does it sometimes look odd when the news is reporting something earlier on the news, so then the formats layer up in a way that they don't match?
That's BTS, not BT. BTS stands for 'Better Tell Shooting'. This is best used when there is a bug in game.
My sister says BTS is a K-Pop band, but she doesn't know what she's talking about. She's never played PokéFind herself, so obviously she doesn't know.
