Human Pickup #2

To answer my previous question, landers that don’t have a human to pick up should just wander the landscape. This is now in place. Landers also now choose the shortest route to a human. Previously they couldn’t calculate distances across the world wrap boundary, so if a human was at position 2040, for example, and the lander was at position 1 (ie. 10 pixels apart), the lander would travel to the right (across over 2000 pixels) instead of travelling left (10 pixels).
