When a player reaches an island by ship, the hex they "land on" gets a production number. However, if the computer has run out of new production numbers to assign, the production number for the newly-reached island hex is taken from a hex in the mainland (i.e now a hex in the mainland has no production number).

When this happens, the computer lets you pick which number from the mainland you want to take to the island. **I would like to know how the game decides which choices to give you.** It doesn't always let you pick from all of the hexes you currently occupy on the mainland.
