let me just make myself clear on this ~really sorry if im bugging ya or something~
i do own a sapphire and i know that trees will not just disappear/died out
concerning the wepear berries~
i picked all of them (3 trees). that gives me 9 berries, no?
next i replanted all three of them. 6 berries left
after a while, i return to that spot and found that theres nothing there. ie. only soil
i've double checked that by looking at my bag, 6 berries. this proved that i've actually replanted them
there's something i want to add into it too. berries grow according to footsteps right?
there's a case which i find pretty amusing
i saved my game in front of 3 nanab berry seeds, switched off my console. after like, several hours later, turned it on and found that the seeds sprouted? o_0~
ps. no one touched my game =)
