This is probably the most annoying thing about the asset editor. Seriously, the inability to attract outside connection citizens (tourists) to a custom asset whether it be a train station, harbour or airport is ridiculous!
I think it's having something to do with the "connectionclass" loading as "null" in the editor, so the class is vacant when the asset is saved.
Although you can still use stations with inner city lines, it renders the airports and harbours useless.
If there are any modders who could try and implement a fix of some sort (whether it be a simple check box within the editor or something) would be great!
