Put the summary of the bug you're having here

What I expected to happen was...:
The Map showing the Terrain outlines and the red Cross

What actually happened was...:
The map acted like an unwritten map and filled out like a unwritten map when I right clicked with it. This happens with all buried treasure maps that I have found so far
**

Steps to Reproduce:
1. Find a buried treasure map
2. You will see that the item symbol is that of an unwritten map
3. right click with te map, and it will act like an unwritten map instead of an buried treasure map
