Steps to reproduce:
# Open a new Unity project
# Switch to iOS
# Open *Splash Image* settings (Project Settings/Player/Splash Image) and change something in *iPhone Launch Screen* section
# Make a build and notice that the changes are correctly reflected in the build
# Go back to editor and make some changes in the *iPhone Launch Screen* section again
# Make a second build

Expected result: Changes made after the first build should be reflected in the second build.
Actual result: Changes made after the first build are ignored. Second build has the same launch screen as the initial build.

Note: If you close and re-open the project and then build again, changes will be picked up and resulting build will have the correct launch screen setup.
