False positive error / warning 'There can only be one instance of Actor type FortMinigameSettingsBuilding in a map'

Summary

At some point the editor has been configured to emit an error “There can only be one instance of Actor type FortMinigameSettingsBuilding in a map”, but it was downgraded to a warning at a later point in time. The error pop-up and the warning log appears every time on save in a project that uses GameFeatureData to compose multiple levels into one.

Additional Notes

For more context:

I have a project which has only static and stationary environment in one level and logic, moving objects and devices as well as scene graph in the other level. Those levels are composed together. This setup is critically picked in order to preserve the environment level at all costs. If a Fortnite update ever happen to break the logic level so significantly which would make it impossible to open the project itself, I want to be able to re-cover the environment level while re-creating the logic level from scratch again. That’s why the GameFeatureData level composition is so crucial.
