ATC directs aircraft to takeoff downwind at one of the airports I updated with ADE version 17. This does not occur using the default airport, so I assume something I did with ADE is causing the problem. I continue to use alpha 17 for this airport due to objects appearing backwards in alpha 18. I tried swapping the primary runway designation and rotating the runway 180 degrees, but that did not resolve the issue. I then loaded it into alpha 18 and compiled and that did not resolve the issue. There are other airports I updated using both versions of ADE that do not have this issue. Any idea what could be done using ADE to cause the problem?
