Help with beginner map creation

Hi all,

I have been using the content editor to create my own maps by using the auto generate option (beginner) and then adding my own things to it.

I havent been able to get trading posts to work correctly. I place them on the map from the object browser com_trading_post_(then I have tried all the different types) but when I load the game they are just there as buildings and not selectable. Basically I can see them but they arnt working as a trading post usually would.

I assume there is some simple step or setting ive missed. Does anyone have a link to a good tutorial to how to get these to work?

thanks
