Add the ability to shift North or South row separately at the beginning of the game so that it is possible to play the linked game of Neanderthal-Greenland. Reminder: for each ice sheet in Neanderthal apply a global cooling to the appropriate row in Greenland (one row, not two rows).
Well, I posted version 2.1 of the module to the Vassal website with this option as well as the other changes indicated in the first post (including extra playing area). It should be visible there in the next few days, when it passes moderation.
Everybody please let me know if you find any issues with the new release.
