Is there any way of determining how many trade routes you are allowed at a given time? I've reached Master Trade tech and assume I can now have quite a few trade routes, but how do I find out how many? I'd rather not keep buildiong freighters and sending them out until I get a screen telling me I've exceeded the limit...that would be a pretty clumsy way to do it. Haven't found anything in the manual on this. Can someone help me out here? Thanks.
