1= Industrial age
2= Ion age
when you are in the 2nd (Ion age) city and you select the ‘GB Investment’ . it will return details for GBs in my 1st(Industrial age) city.
Hope this helps
IF not when I view the source of the page where can I find correct URL for you?
If on 1st City with lots of GBs it should display them
if on 2nd City only Oracle of Delphi it should not display GB from 1st City
