EDIT: Unity Issue Tracker - [Addressables] Build system does not detect ScenePostprocessor changes
The Addressbles Build System does not detect changes to scene postprocessors, for example when a new scene postprocessor is added. It continues to use cached build artifacts in this case, causing the build result to be wrong.
You need to perform a “Clean All” for Addressables to build the correct stuff. This is obviously not good, we don’t want to “Clean All” every build, because it causes the build times to skyrocket. At the same time, “New Build” doesn’t detect such scene postprocessor changes and potentially builds the wrong stuff.
Please see below video for a problem description and bug-report Case 1297713 for a project to reproduce.
I tested Unity 2019.4.16f1 and Addressables 1.16.15.
