its easily fixed, which is probably why its not been fixed yet. Tho if i remember right, all these kinds of problems are going to be fixed in 1.04
go to
\Victoria\scenarios\GC
and find switzerland.csv
open this in excel (or anything else that works with csv's)
delete line 31:
10;Swiss;Protestant;farmers;;;;120
no more swiss in the ross river.
To fix the other 2 pop problems:
rockhampton, austrailia:
\Victoria\scenarios\GC\eastaustralia.csv
change line 2 from 2747;British;Protestant;farmers;;;;0
to something higher than 0... say 2:
2747;British;Protestant;farmers;;;;2
fogaras (south east austria)
go to
\Victoria\scenarios\1836.eug
add the line
pop = "scenarios/gc/siebenburgen_east.csv"
somewhere near the bottom.
