Update: This was at FSDT KIAH where after editing/customizing KIAH by adding a few parking places with ADE 1.78.
Jetways would not dock to AI aircraft after editing airport.
ADE assigns its own file name, eg: KIAH_ADEP4_ADE_xxx.bgl
I usually add a date and assign a number, eg; KIAH_ADEP4_ADE_110823-1.bgl
When I did this, compiled the file, and then copied the file to the KIAH scenery folder the jetways would not animate.
I changed my file name back to the original file name; KIAH_AIP_FSDT.bgl (with my changes) - and low and behold the jetways all docked to AI aircraft.
I am using default jetways.
