I had taken the note in B-6. On the side quest sheet, it said that there is a chest near the teleporter in D-4. I have searched all over D-4, even went behind the barrier and couldn't find the chest. Then, I started checking all the teleporters. I saw a chest near the teleporter in D-7. I opened the chest and it had 400 onyx coins, just like the sheet said. Is this a typo on the sheet or is there a chest in D-4? Thanks
