It took me like 3 hours to find it a few weeks back, its on the North East side. The entrance is under water in a glacier. You swim through its winding tunnels and you get in. Though I cant really recommend going, with all thew mesh changes. The cave has a pretty good chance of out right killing you because it thinks you are leaving the map.

Anyone have cords to this?

Yep, don't go in there, lost all loot and more. Was put into a terrible spot.

Has this been fixed?

I found it, and the glitch has been fixed I guess. I went down no problem and retrieved the artifact. There is a lot of graphics to render in. The rendering was a bit glitchy, so i took it slow and let stuff render before progressing when I saw light/ sky looking areas. I don't want to give out the cords on someone else's thread when he chose not too. But it is in the area where the Ice Island wraps around to the main land. I spent a lot of time looking for this cave location both in map and on line. This was the only post I found that gave the right area much less cords to Olympus Map Cunning Cave location. You might have been the only person to correctly find it and give a hint to its location. Coodo's
