I'm at the last door before meeting Joko and the door remains closed after I turned the symbol. What am I missing?
Is this the mission that gives you a skill to see through Joko's illusions? Did you try using it on the symbol?
I've had playthroughs of that mission on a couple of characters where I had to, like, solve the puzzle twice. They all looked lined up correctly, but nothing happened. So I moved each of them and then re-did it and got the door to open and all that. Maybe you got into a similar state, where what you see and what the game thinks are the positions of the symbols don't agree (assuming that's what happened).
have fun and be excellent to one another
I'm thinking that's the case. Even though I thought I had turned the symbols correctly, I must have missed at least one because Braham isn't with me. As much as I hate to (I'm VERY bad at jumping), I have to start over.
