World Update XVIII: Germany, Austria, and Switzerland includes an Asobo enhanced version of Munich Airport. Due to this, having both the World Update and sim-wings Munich installed will cause two sceneries to be active at once, causing a conflict which may lead to issues such as uneven terrain.
To fix this issue, you will need to delete the Asobo enhanced version of Munich Airport. You can do this by performing the steps listed below:
- From the Microsoft Flight Simulator main menu, select PROFILE from the top navigation bar, and then CONTENT MANAGER.
- In the search bar that appears, search for World Update XVIII. Hover over the World Update XVIII result and click the blue icon that appears to the right of the entry.
- Scroll and select EDDM MUNICH AIRPORT from the list, and click the delete button.
- The world update version of Munich will now be removed, leaving only sim-wings Munich installed. You may have to restart your simulator after this process to fix any remaining ground texture issues.
