I think this looks correct, can you tell me which ways this has been tested?

ie:

• claimed a town following the rules with adjacency enabled.
• claimed an outpost in a world where they already have their town.
• claimed an outpost in a world where they dont already have their town.
• attempted to claim a 2nd outpost.

• The goal, allowing the claiming of a 5th chunk after a 2x2 on the new world, has been accomplished
• expansion is still prevented after 5 chunks in the target world if it doesn't follow the min adjacent requirement
• successfully claimed an outpost in a new world, expanded as mentioned above
• successfully claimed a second outpost in the same world, rules of adjacency still limit expansion (The outpost adjacent exception still works)
