Out Of My Mind

Do someone know how to do this quest? After this update its literally impossible to do. I looked everywhere beneath the Great Bridge, tried to put emeralds to red carpets because i thought that they have a hopper, tried to wait until night for that door to open, tried to go to the door after those dialogues, tried switching servers and do the same thing and still nothing. And 2 hours doing this for nothing. Please fix this ASAP.

 

You're looking super far away from where it actually is. Try searching around near the Undergrowth Ruins Dungeon (Previously Jungle Dungeon) with your key.

 

But the NPC told me that I need to go there >:(
