OpenStudio 2.9.1 on Windows 7 Pro just tossed this error at me from the OpenStudio Results measure: "Interior Lighting Summary section failed and was skipped because: Optional not initialized. Detail on error follows.". Has anyone seen this before? Any fixes? Does this mean that other results from this measure may be suspect? Are the EnergyPlus results still trustworthy? I think I am still using a measure version from before 2.9.1 - Could that be a problem?
