I am stuck in the Underwater Labyrinth trying to find the pearls to get to the sunken ship. I believe I have cleared the entire outer section of the maze (including the north and southwest areas accessible from the rolling boulder areas), and can only find 6 pearls. I have checked my map for items left in chests (found none). Any help would be appreciated.

Adding a map in case someone sees something I missed. There are three places where I left junk. and 1 herb I left.

I have attached your map where I marked the chests, which should have the 8 total pearls. Looking at your map, I assume that you have used 7 of them. Make sure to check your inventory, if it is not under some of the items, since these are very small. I would check the stuff that you have thrown away again as well. Hopefully, this is not some kind of bug, though.

Found it. It was hiding in inv, but I thought I searched that area. Thanks.
