Well, to continue confusion ...
There is an update of the "BWEP AI Traffic" dated 01.04.2018 in "Download and Installation Table":
http://return.mistymoorings.com/bwep/index.php#MaintenanceUnpacking this "BWEP_AI_Files.zip" file you'll find in there "BWEP_Heli_Traffic.zip"
- in there you find a versions of "Traffic_Heli_BWEP.bgl" dated 2016
- in the folder \BWEP_Heli_Traffic you'll see another versions of "Traffic_Heli_BWEP.bgl" dated 2018.
I opened both traffic versions in "AI Flightplanner". In the aircraft list there is no texture file "N2062MM" shown as needed but
- N2063MM
- N2064MM
Conclusion:
If you only have the texture "N2062MM" installed in "AI_Rotorcraft_Bell_206L_TFX" the "AI Flightplanner" will show missing texures (i.e. N2063MM and N2064MM) and in your scenery no BWEP AI helicopter will be displayed as AI traffic.
