I've found myself getting soft-locked a couple times because of this but if you set an infernus that needs to blow up to open a door or gate, eg. Gates of Saturn or Gods of Battle, if you set them on fire with a fire arrow or the spear ability they don't actually destroy what they are intended to destroy. Not sure if this is just a GameCube thing though.

Probably the GameCube thing, I don't remember ever happening to me while playing on Wii console. Thanks for sharing.
