I received the following message when building a model. I dragged a Finished Attic over a previous Living Space in the GUI to trigger this result. Model included here. I repeated the error, but the second time by extending the 1st floor living space, rather than converting the space type.
Message: The following application error has occurred in BEopt v3.0.0.0. Please report this to the BEopt development team and restart the application.
Destination array was not long enough. Check destIndex and length, and the array's lower bounds.
