SPOILER Possibly Undiscovered New Island?

I found this wrecked boat in an underwater cave near the tower (coords are writed) didn't find anything special except a loot chest :

This can possibly be the boat of the painter

Explored a bit more and found this at the top of the falling water, 3 gold pressure plate, activated them with one emerald each, nothing... :

The pics don't appear for me, if it happen to you too : https://gyazo.com/3523ee5dd18c466d5fd2f8c6512e38af

 

Goddamn trolls =P

(The guy is named Troll so I just- ok..)

 

When you jump from the top of the tower to the little tank of water at the entry of the tower, you will find this (With a T2 chest) :

 

I'm IN THE PICTURE
YEAAAAAHHH

 

Nice find! Never went there, that is probably new to the update.

Refering to the pictures, when I post I always click the 'preview' button, and there I can see all the images. If you do that and still don't see 'em, don't really know what to do.
