if you have a problem with kyogre event that it is not happening for any reason check what I wrote a little while ago to mr swag sire. If done correctly it should work
Oops nevermind was in another thread so imma post it here aswell.
"hey sir swag I might have found a way for you since I had same problem, first off when venam goes down the ladder don't go to her yet just go to to other ladder and continue, you will get the emotion powder or w/e its called from ???, after that change the mood to ice , but do not return to venam, first after you turn it to ice and water go on your left and surf, fight the guy in there and turn the red crystal ,, after that go to venam and yu will see event were she talks and tells you to change the mood etc, after she done talking go back were the ??? guy was and exit the cave, then re-enter the cave and go change the place to ice and only then return to venam, this trick should work I hope^^ "
