And this lets me get a dig in on Other M as well!
If they designed this like a REAL Metroid game instead of having arbitrary locked doors and disabled abilities that open when the game says so then maybe such a bug wouldn't exist. The bug is more or less triggered by someone playing Metroid like a Metroid game!
The door is locked because it's in the same room as a boss fight--after you beat the boss the door opens. They had these types of doors in Super Metriod.
Think before you post.
If I remember correctly, isn't the door in question in the large chamber with the 3 Grapple Points and the lava monsters just after you take the elevator down from defeating that boss at the top of the oil refinery? If it is, there's no boss fight there.
