In the attached project, an animation controller is present with missing parameters - this causes errors to occur during the building process. When building however, the build result will be different depending on whether you using Build or Build & Run

Build - Errors appear during the build process but the build is successful and the files are deposited in the build location

Build & Run - Errors appear during the build process, the build fails and files are not deposited in the build location

1. Launch Unity
2. Open the attached project
3. Open SampleScene.scene
4. Create a build using File > Build
5. Create a build using File > Build & Run

Expected Result:
The two methods of building should yield the same build results.

Actual Result:
Building via "Build" is successful, but building via "Build & Run" fails.

Tested on Windows.

Occurs on 2017.4.f21, 2019.3.0a2
