Put the summary of the bug you're having here
What I expected to happen was...:
I would start in the center of the map and it would be filled in as I explored
What actually happened was...:
The map completely filled in from left to right and showed I was on the edge of the map. (I think it just loaded the chunk I was in)
Maps put in a chest and retrieved later are blank but still show player position and movement but do not fill in with terrain.
Steps to Reproduce:
1. Create map using compass and paper
2. Hold map in hand
3. Right click with map in hand.
