Hey
@Devilofcain
Once you have the four plates, make sure you insert them in the mechanism that's down below, where the dogs are (near the area where the sewer key was in the mission 1)
As for that bug, can you tell me what you did for it to happen? I mean, did you die and retry or something like that? maybe you went back to the exterior and back to the sewers again?
I've been unable to reproduce, so any specific info can help me a lot to find out what's causing it.
Thank you very much for your words!
