I suspect it has been a long time since you last updated KoLmafia since that location was added to the program in Mid-October. Lots of stuff won't work quite right for you. Since Crimbo is a time when stuff is being added daily you really don't want to fall behind the update cycle.
A minor nit, which might be an opportunity to correct KoLmafia's data, rather than a problem with the script.
It reports that I have not encountered a "drunk duck" at the Farm. But when I look at the KoL provided progress report there is no such monster. There is, however a "mean drunk duck" in the list and that is how it is labeled in the relay browser.
