Yes i have the same problem.
All right then, let me ask you another way. Why am I having the problem with KMRY? But no problems like these with KEGE and LOWI.
By the way, I was able to solve the problem with the sunken aircraft by myself.
Please service pack for KMRY orbx.
Aerofly FS2 Aerosoft Box has been updated to version 2.00.11.05.
Owner of the Aersoft box can obtain the update from the Aerosoft Support Database and via aerofly.aerosoft.com.
This update solved also this elevation problem.
Thank you very much to all who worked for it!
Now my flight simulation world is alright again!
