What steps will reproduce the problem?

1. Set min_adjacent_blocks in the config to 2 or more
2. Claim an outpost, fill in claims around it
3. Do /t unclaim until you can no longer unclaim and get the error message, "You cannot unclaim this townblock because the townblock at x,z would not have enough adjacent claims (2 are required)

What is the expected output?

You should be able to unclaim an outpost fully

In conversation in the Discord, Warrior suggested, "it could probably re-use the logic from /t claim fill for selecting only attached blocks for the claim count"
