Warning when packaging: Steam API disabled!

When we package our project, we do not get errors, but within the first ten lines in the output log, this warning appears:

MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: LogOnline:Display: STEAM: Loading Steam SDK 1.32
MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: LogOnline:Warning: STEAM: Steam API disabled!
MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: LogOnline:Display: STEAM: OnlineSubsystemSteam::Shutdown()

What could cause the Steam API to get disabled?

(We used [this wiki entry from ][1] for integrating Steam to our project, everything, except Server Travel ([same issue as in our previous project][2]) works in the packaged project)
