there's also a minor bug that i found regarding manipulate, dragon force and the dark dragon at the northern cave. for some reason, when you manipulate the dragon and try to use dragon force on the party, the game only lets you use it on the very first character. it doesnt let you at all change the target. its very minor since you have to put the person with enemy skill on the first spot of the party, but id did not go in too many dephts if it just affects the dark dragon/dark force or if its a manipulate thing. for what its worth, from the other uses i gave to manipulate, its the only time that ever happened to me.
the game is also crashing at the safer sephiroth battle. probably due to a counter? i had aerith use comet2 with w magic and from what happened, the game crashed after aerith finished casting the first comet2. so since she didnt even start casting the 2nd comet2, im assuming safer sephiroth countered the first comet2 with an attack that caused the crash. seems serious to me.
