I figured it out - you aren’t allowed to have a radar antenna on top of a tunnel. I’m not sure why - maybe it’s a bug?
How do you host a game with a custom track? My track shows up in the "Make a Track" menu but not in the "Host Game" menu
Can you let us customize how many "states" there are and what the names are? I like the idea, but the current cycle doesn't really match my workflow.
