Yes, there is something amiss. My explorers have discovered several British tiles with former British cities nearby (Welsh, Scottish). However, there are no British forts nearby to explain why the borders remain British. If recalculation had taken place, then the tiles would have become either Welsh, or Scottish, or unclaimed territory. Hmmm.
