okay heres number 1, it's a battle UI bug i believe.
poke1 feints, swap to poke2,
if you notice top left the UI shows poke1 is still alive (normally around 50% hp)
swap to poke1, use item, poke1 feints. (some occasions poke1 will just feint right away)
swap to poke2.
the second bug i enounter is with the Pokedex, it seems to be a visual bug.
if i pull up Bubasaur (seems to be every poke in the dex) you'll notice his/her hexagon shaped base stats is dim,
i noticed when you highlight 001 in the search bar the hexagon lights up.
