I can confirm the problem with KSEA. I have in P3D v2.0 runways in the canyon! I use "FTX Global Base Pack 1:20" and "FTX Vector Pack 1.10". This problem occurs after you install "FTX NA PNW PACIFIC NORTHWEST V1.0 Patch 008". I am grateful for any solution idea! Greetings Frank Sorry for bad english (made by google).
