I need help regarding this problem. It all started because I wanted to add a window components to my model. At first, I put the window components to the first story of my building and successfully merged it. Then, I put the window component to my model's 2nd story and merged it, there's still no error. After that, I tried to change my model dimension by erasing some of the areas with the window directly using erase tool and then merged the model with new dimension. The error started from here. After I merged my the model, I can't see nor edit the 2nd story of my model because it isn't showing up. Every time I merge the model, my OpenStudio force close. Is there anything I can do to solve this problem? It'll be a pain to model the building and it's system from the beginning
