Is there any special reason why the balance of doors, encounters and geographic has been changed in the mapping game compare the book one?
Or is it just an unintentional accident that happened by just having one of each counter variant?
Since when drawing from the different counter pools, as instructed to do, it has a different probability then when using 1d100 and the tables in the book.
Some door examples (book vs map):
* open door: 40% vs 26%
* each other type: 10% vs 12.3%
* etc.
Some encounters examples (book vs map):
* any of the first 4 encounters (1-30): 30% vs 7.5%
* any of the last 30 encounter (71-100): 30% vs 56.6%
* etc.
Some geographical examples (book vs map):
* any Barrels (12-15,33-35,50,72-74): 11% vs 7%
* any Levers (23-24,36-40,52-53,75-77,84-87): 16% vs 8.7%
* any Chest (19-22,26-29,42-43,45-48,55-58,78,80,91-95): 25% vs 5.7%
* etc.
For the missing cards, I chose 4 areas that was a duplication regarding colour and exits to other ones from the table. So you could find the ones that match the layout and just replace the numbers.
