This occured at VVTS Gate 13 default scenery with PMDG B737-900(WL). My sequence was Catering then Fuel then Boarding then Pushback. I kept getting text that Baggage was still being loaded long after trucks had left and passenger boarded had completed. Finally I got one last msg again that Boarding had completed and this time allowed me to request Pushback. But as you can see from the photos the front conveyor pulled back after completion but the rear conveyor stayed in position. Also the rear stairs did not pull back far enough so that the left wing would clear it. These photos both taken as pushback already started. BTW, I am using version 1.3 + last update (VISTA 64/FSX SP2/Quad Core)
