Like, I built everything I needed to in a simple, 2 station loop. The tracks are connected, I have waiting areas, tracks are set up to work in a unidirectional, and the goods stations are set up to send/receive as necessary. But everything says it isn't connected, even though it is!
Except, one of my two goods stations doesn't have the error- the one next to the train yard. Everything else has the error. The only thing I can think of is the ramps are bugged- that's the only difference I can tell between what is and isn't working.

I love this mod so much, I just can't get my train to go choo... sad day.
