I'm having trouble with the third gym

[Lardking]

Hey forum,

I've defeated Team Meteor's Tangrowth, found the third gym (poison) north of the pokemon center, and did the light tube puzzle.

However, when I enter the "secret" door, all I get is the poison battle field, surrounded by more tubes, regardless of the first room's tube colours upon entering. I've looked online for a solution (including this forum), and apparently I'm supposed to enter Corey's chambers instead.

Is this a known bug, or did the requirements for solving this puzzle change? If so, could you please tell me what I'm doing wrong? As I said, all walkthroughs and LPs on Youtube don't have this problem, so any help would be appreciated.

Are you sure you have done the light tube puzzle correctly? A secret door should appear near the light tubes - where Corey should be waiting

If you've completed the puzzle, a door will open in the back wall, just behind the tubes. It'll be on the right hand side.

To complete the puzzle, you need to change all of the tubes to the colour that they aren't when you first walk in.

I've done all of this.

I completed the puzzle, went through the door at the back...and there's the poison battle field, not Corey's chambers.

Wrong door at the back. A new door should open up on the wall in the middle of the room.

Woohoo, got it. Now I feel stupid :/

Thanks a lot.
