Another bug I've seen in Pirates, I can't tell it happens in other large maps too, or it is specific for this variant: the large map show wrong colors!
Most times it's only non-sc provinces, but it often happens with supply centers...
E.g., check the final map for
gameID=31802 and compare it with its large map:

gameID=31802&turn=18&mapType=large
The colors of the following provinces are wrong only on the large map:
Crooked Island Passage (CIP)
Caicos and Turks Island (CTI)
Hispaniola (Hisp)
Guadaloupe (Guad - supply center)
Cunana (supply center)
