I didn’t experience this exact issue, but I did notice that during my landing last night using the mod, after I started extending the flaps for landing, the A320 did not want to lose altitude. However, my airspeed got really low, like around 120 knots which meant I had to apply a lot of power to keep from stalling. Of course, this meant losing altitude was tough, and I nearly landed too high but manage to get the aircraft on the ground.
I never used to have this issue, so it must be something new with the flight model after the update.
