During the "Vogelstruijs" quest, you burgle the captain's house and steal a letter. Here's the letter's description:

It seems that the code which reads quest documents is failing to interpret the variables. I changed the file, replacing one of them with a hard-coded name, which then appeared correctly and proved that I was in fact looking at the correct file.
If the code can't be fixed to read the variable correctly then the towns may as well be hard coded as Port Royal and Santo Domingo respectively because when the towns don't have those names, the quest makes no sense anyway. In "Early Explorers" Spain doesn't need to take #sRedmond# because it's Villa de la Vega and they already own it. If #sRedmond# is Kingston then Port au Prince doesn't need to fear war with Spain because it's already happened, France won, and the result was the ceding of Spain's portion of Hispaniola to France, which is why #sSanto Domingo# is now Saint Domingue.
