"The Addon <unknown> is causing the Couatl Scripting Engine to restart" errors

Hello,

I keep getting a panic log with the above titled error message every time I attempt to launch GSX within MSFS. So far it has happened at 3 different airports, some default/some addon airports. What is causing this error to show up?

Incomplete install, as explained here:

Hello Umberto,

I didn't want to open another thread as I received the same error today, but I think mine might be a bit different.

After landing in Rome (LIRF) I used GSX to deboard the plane, but I didn't wait until it is finished and exited to the main menu. This was the time when the mentioned error appeared.
Could this be related to me prematurely "closing" the world and GSX trying to spawn passengers in it? On the other hand I updated via the FSDT Installer yesterday and everything looked fine so I assume that my install is complete.

Log is attached.

Cheers Phil

I didn't wait until it is finished and exited to the main menu. This was the time when the mentioned error appeared.

That's exactly what caused the error, exiting to the menu when passengers were still being created. The next update will prevent this, by restarting the program as soon as you exit to the main menu, because when there's a loading bar in progress or the simulator is returning to the menu, commands to create new objects are not accepted and will return an error even if the object exists.
