"Error: Error: readBND, Did not recognize: Controlled Zone Return,1,CORE_ZN RETURN AIR NODE NODE NAME."

After updating small_office.idf example from energy.gov from v7.2 to v8.8, running a file via MLE+ gives this error; while energy plus .err file there is no errors. AFAIK the problem lies in a class ZoneHVAC:EquipmentConnections.

ZoneHVAC:EquipmentConnections class:

! ***CONNECTIONS***

ZoneHVAC:EquipmentConnections, Core_ZN, !- Zone Name Core_ZN Equipment, !- Zone Conditioning Equipment List Name Core_ZN Inlet Nodes, !- Zone Air Inlet Node or NodeList Name , !- Zone Air Exhaust Node or NodeList Name Core_ZN Air Node, !- Zone Air Node Name Core_ZN Return Air Node Name; !- Zone Return Air Node or NodeList Name

You should search the input file for "CORE_ZN RETURN AIR NODE NODE NAME" to see where that text exists. From your connection node names above, I don't see a node name with "NODE NODE" in it.
