Cook fails

Using a build from github (SHA: 3ff2714) I’ve stumbled on an issue when trying to package:

LogClass: Error: EnumProperty FNiagaraPlatformSetRedirect::Mode is not initialized properly. Module:Niagara File:Classes/NiagaraPlatformSet.h

There are more of similar issues. These used to produce warnings as far as I remember but seem not to be errors. The result is that the cook fails. I should say that I’m not 100% sure if this is the issue but it is what I can see as errors in the log anyway.

Does anyone know if this is possible to circumvent? I’m not using Niagara.
