When a HVAC VENT is removed, Pyrosim prompts a question "Vent references will be removed. Would you like to continue?". If said YES, then the VENT is removed from the HVAC entry. This makes sense.
However when I undo it (CTRL+Z), then the VENT is reappers but HVAC entry is not updated. It stays as the replacement, Ambient.
Is there a reason this should work this way or is it possible to fix the HVAC entry as well when I undo the removal operation?
