Not too much of a bug, because it’s no coding error but something confusing and annyoing.
At Brussels Intl there are three physical runways, 25L/07R, 25R/07L, 20/02. At one point 25R and 20 cross over, near the end of each runway. This caused confusion on live as people thought they were on 25R but they were on 20. This was the advanced server.
