Bug report: I have version ALPHA v1.0.114.0

I get 550 exploration xp whenever I "discover" the area at x227 y354. I can go out, go back in, get the xp, as many times as I like.

This is a known issue due to the companions.

And it's not the only area. Almost all areas you discover - you can walk circles and get exp.
The end of Black Cave - where you fight the undead and then resurrected pirates - gives ~17k exp - you can run around and keep getting and leveling like crazy.

But as already mentioned - its a known issue.
