My plane lands on an east-west runway. Instead of taxing to the far east end upon landing, it turns on taxiway, reverses and taxis back up the runway to where it landed (west end). This began when I added a 4th and 5th Small Stand. When I had only three Small Stands, it operated correctly.
This problem is causing delays, because the runway must clear before another plan can takeoff or land.
I do have a parallel taxiway. When the jets land, they go to the far east end of the runway. Instead of turning right onto the taxiway, they rotate in place and go back to the west end where they landed. Earlier, with this exact same setup, the planes exited the runway on the east end onto the taxiway. Then, suddenly, they stopped doing so.
