Stuck door in boss room

[TheWood]

This door sometimes does not open when the player approaches.

[Robby]

Which door are you referring to exactly?

[TheWood]

Pink door in the arena with boss in area 91.

[Robby]

The door in the front of the area or the door in the very back, leading to the lead scientist?

Door in the back.

[Robby]

Ok, that door is actually supposed to be that way. It only open for a short time after the boss is killed.

There is an NPC in area #91 that should tell you about the door.

[TheWood]

I see, but it sometimes does not close completely leaving a low passageway through which you can no longer pass.

[Robby]

Oh ok, strange. Would you be able to take a screenshot?
