Hi,
I would like to share an easy fix to the issue.
1-Create an extra instance for special situations (this included).
2-Check on the market locator (ML)-countries-"search internationally"
3-Create a file with a list of competitions from the countries not listed.
4-On the ML create the condition: "Market's name contain values in file...(the file you created)"
It's not as good as the fully list of countries, but, i guess, while the list update is not done, it can help.
