There are rare cases in Elfenland, where it is not possible to move away from a certain place for the whole remaining game. E.g. if you are in the desert city and you have no transportation cards for desert terrain. As you cannot play some cards, they never get exchanged. It seems not to be described in the manual. What would you do? Exchange the players cards?
Are you playing with the Caravan rules? From the rulebook:
As I understand it, Elfenroads did NOT have this rule, making it easier to get stranded. Apparently some people hate the Caravan rule because it means players don't have to be supremely careful not to get themselves stuck any more...
