the current Pacific 1940 can only be played with TripleA 1.4, and not with TripleA 1.3.2.2.
the errors you are seeing is TripleA 1.3.2.2 telling you it does not understand the map. The error does not cause any problems to any other maps, or to triplea in general. the error will simply stop you from playing pacific on 1.3.2.2.
Solutions:
Solution 1: ignore error, close it every time it shows up
Solution 2: start using triplea 1.4 instead of 1.3.2.2
Solution 3: move the offending map zip/folder OUT of your
users/triplea/maps/ directory, and put it in your program
files/triplea/triplea_1_4/maps/ directory. This means the maps will only
be available to triplea 1.4, and not to other versions of triplea (and also
means that 1.3.2.2 won’t see them, and won’t generate the error).
Solution 4: delete the offending map (not all maps, just the one with the
new features that 1.3.2.2 doesn’t have)
