Volt Switch/U-Turn: When it KOs a wild Pokemon, the user is still prompted to switch before the battle ends (EXP is distributed correctly, though). This doesn't happen in the main series games.
Beat Up: In a double battle again two separate trainers I don't believe it should count both trainer's Pokemon.
Ex: Player vs Trainer 1 and Trainer 2, each with three Pokemon. Each has one Pokemon KO'd.
Houndour used Beat Up and it hit four times.
I believe it should've only hit twice.
