This one has me stumped, and it looks like it's been an issue before, so I'm hoping someone has an idea. I was building a model in the wizard and went to save-as before something got screwy, and it appeared I was too late. I got an error for multiple zones that read "MULTIPLIER in XXXzone has Expression Evaluation Error: Invalid BDL reference", followed up by a bunch of zone errors stating that they were "referenced but not defined". I did some searching and came up with a few hits, but no solutions (that I could see). I bit the bullet and went back and tried to rezone it from my last save, and while the error seems to occur for different zones, I still got it. I went through and tried to purge out some AHU's and spaces that may have pushed me up against some limit I'm not aware of, but nothing's helped so far.

Below is what I'm currently zoning, and you can see that in the building footprint screen, there are zones that I've defined that aren't showing up. I'm attaching the pd2. Any thoughts or ideas would be appreciated!
