I have a model with 40 or so zones and it has evolved over the past weeks. During one evolution, the outputs in the E+ table, the zone names in the idf file, and outputs in the SQL file are labeled by Zone handle (e.g. the long random characters) instead of zone name. This is happening to only about 1/2 of them. In the OS input environment the zone names are always displayed - not the handles.
Has anyone seen this?
