Error when selecting services at VQPR

[Mik75]

Hi!
Tonight, I got an error message upon requesting Boarding at VQPR (FSDG Paro).
COUATL had to be restarted and the following log file has been created:

couatl v3.0 (build 3187)
panic log started on Mon Apr 04 21:20:22 2016

problem raised by addon <unknown>
Traceback (most recent call last):

What went wrong here?

The "cruise speed must be positive" has been discussed many times on the forum ( you could have searched the forum for "cruise speed must be positive" ), for example here:

This error indicates the scenery AFCAD has an error, like overlapping nodes, orphaned nodes, unconnected links, unreachable parkings, etc. You might try to fix it using the ADE or AFX "Fault Finder" options, or at least having an idea what's wrong with the AFCAD, and report it to the developers.
