Thanks Blaze and no problem, I get some personal satisfaction from the idea that folks enjoy the work, so I end up actually creating more content and it's a win-win. Onto your problem - I know what part of the code is hiccuping here and I have some ideas as to why.
Please check your races.gd file for the lines between #ralph5 and #/ralph5 under each race (you don't need to check all of them, I expect it's there for all or none):
var races = {
Human = {
skin = ['pale', 'fair', 'olive', 'tan'],
...
pricemod = 1,
#ralph5
marketup = ["Demand for [color=aqua]humans[/color] rises inexplicably.\n"],
marketdown = ["It seems [color=aqua]humans[/color] aren't being purchased very quickly. Prices fall.\n"],
single = "human",
plural = "humans",
singlepos = "human's",
pluralpos = "humans'",
#/ralph5
In constructor.gd, you should also have:
func changerace(person, race = null):
...
if i in ['marketup', 'marketdown']: #ralph5
continue #ralph5
If either is missing, you can apply the latest patch that applies to your setup (base or tweaked) per the instructions (just drag&drops again) and that will hopefully fix it by replacing the races.gd and/or constructor.gd files. Please let me know whether it works or not. If not, we'll go to the next step.
