Updated this morning with AddonManagerUpdate exe.
From your screenshot, it shows you still have the outdated vehicles, which is normal, if you *really* updated with the Addon Manager only. As indicated in the Couatl Live Update release notes, that are presented to you when a Live Update notification happens:
http://www.fsdreamteam.com/couatl_liveupdate_notes.htmlIMPORTANT: this update requires to download and install the latest GSX FULL INSTALLER!!
So, even if this is reported as an Addon Manager update, it's not enough. ALL vehicles have been updated, to support non-standard ground elevation airports (like Gran Canaria, La Palma) so, the only way to get all their correct versions, is with the FULL GSX installer.
I performed the update hoping you fixed the sunk vehicles and aircraft at KDFW but this has not changed. Picture:
Of course it hasn't changed, it's how the scenery is made. Nothing to do with GSX, although with the new GSX version we might be able to tune the elevation by scenery a bit. But it won't change the fact the scenery IS made in layers with slightly different altitudes, to prevent flickering. Later sceneries use different methods, but since KDFW was the first scenery we made using native FSX materials, it's a bit rough in some methods. It cannot be entirely fixed, without a major scenery update.
About the supposedly missing last vehicle in the cart:
nowhere is said the carts are *always* 3!! Their number can change from 1 to 5, depending on the airplane actual station load, which affects the calculation of the estimated number of passengers on board, which affects the number of carts. GSX has always been like this since it was released. So, if you think you are not getting enough carts, check the airplane load.
Note that, the weight is estimated when you start a GSX procedure. So, if you must change the load, be sure you do it before calling any GSX services.
