Hi Manuel and Jo,   I had the same duplicated jetways issue with the latest v1.11 update and AES. I fixed it by disabling the file ENGM_placement.bgl (renamed with extension .off) in the Mega Airport Oslo 2.0 scenery folder. This file actually sets the static or animated jetways and Oliver apparently forgot to disable/exclude it in his AES utility. Enjoy this new Olso update!   Cheeers, Frank
