Strange Couatl error at FSDT CYVR

[Charles246]

AC. Real Air Duke
Airport: FSDT. CYVR
Parking: B1 South Terminal
FSX Version: Steam

I had parked and engines off. Requested Ground Services: Deboarding. Got the following error. Retried and got the same error. On the second time I said "no" to restarting Couatl and was going to take its suggestion to update it from FSX drop down menu but only the Addon Manager was there.

Could be just a fluke because I normally do not have any errors at YVR. When I re-started Fsx, the Couatl menu was there and the update link suggested I would be reinstalling the same version of Couatl so I declined.

An unrelated question:

The followme vehicle takes forever to come to the South Parking at CYVR. Any chance of having a "second" vehicle parked closer or an awareness in the code that when one parks at the South terminal the Followme vehicle is parked in that area?

Thanks. Merry Christmas

We'll check this, since those error are usually AFCAD errors, and there shouldn't be any errors in our AFCADs...

Thanks. It might have been an aircraft caused error.  I remember when the engine was shut down, and mixture off, I accidentally  turned the magneto of one engine to the right instead of to the left.  I think a glitch in the programming of the Duke, keeps the propeller turning lazily round even when I finally turned the switch off. GSX ground services  I believe had already commenced and this may have initiated that error.
