I would first like to say I love this scenery. Very nice job! I am having a problem, though. I was taxiiing to rwy 28 from Terminal E. Everything was fine. When I got to the rwy and tried to enter it, my aircraft bumped, as if it has gone over a large obstacle. Then my aircraft was floating in the air over the threshhold of rwy 29, about 4-6 ft. up in the air. I have ensured I have no other AFCADs installed for LSZH. Anyone else have this problem, and how can I fix it?
