I have set up a multiple industry to produce brick clay and got it to successfully load wagons which are brought to it, at the other end of the track is the built in brickworks which has two tracks, one for the output of bricks and delivering coal, the other is a clay dump.

When I try to automate the consist to load then route to the brickworks to deliver the clay, I am unable to select the clay dump as the destination, its there but clicking on it has no effect and it jumps back to the other option in the industry pop up. I have driven the line and the are no breaks in it.

Does anyone have any ideas on how to fix this?
Thank you.
