Hi,

I am using equest for the first time, working on a eight storey Library Building with approximately 750 zones (including plenums) and different HVAC systems. The model has multiple plenum spaces and zones allotted to each space. I started deleting few of the thermal plenum zones (for unconditioned utility areas) and the spaces started disappearing, in all the previous versions as well. Eventually, the spaces deleted from all the previous versions as well. Height of the wall is whole floor to floor height, editing that is not fixing the problem.

Please let me know how do I fix this. Thank you.
