Stuck - modded map and civilization

[speeduk]

Hi guys. I have made a huge custom earth map and want to know how to play as the spain civilization that I downloaded? It works when i uncheck "load scenario" but shows "random civilization" if I check load scenario?????

This is driving me crazy as I have placed spain properly and it shows up in worldbuilder etc.

Here's a suggestion: In World Builder, there is an option off to the left that says "Edit Plot". After clicking that, an option should be revealed that reads "Start Position". Select the tile that you wish to have Spain and set it as the starting position of the Spanish Empire. Once you start up your scenario they should be available.
