Squirrel.Windows: Releasify looking in the wrong place?

Upgraded from 0.9.2.1 -> 0.9.5.1 hoping to fix the nuget reference issue thats been breaking our updates… and now I’m getting this during the releasify call on CI:

Releasify just stops there so no new Setup.exe is generated and RELEASES isnt updated. I do get the .nupkg though.
