I think I may have temporarily resolved the problem. The issue boiled down to which version the MTH150.osm file was saved as. For instance, when I originally ran the measure (successfully), the MTH150 was saved with version identifier 1.10.1, but I must have edited some things in the GUI and it must have saved as 1.11.0. The errors occurred because there are several differences between versions 1.10.1 and 1.11.0 when considering the object 'OS:Sizing:Zone.' The attached document shows the differences in their definitions. As far as the error message is concerned, I'm assuming that there is a handle defined somewhere that points to version 1.10.1 instead of 1.11.0, and because 1.11.0 defines the OS:Sizing:Zone object differently, then the error was struck. Due to the error being struck, it pretty much nullified the entire MTH150.osm file, and when attempted to be retrieved in the measure, the measure failed. I resolved this issue by just defining a new unit heater in version 1.10.1.

However, the issue remains that there is a version discrepancy, and at some point, I probably need to use only 1.11.0. Unfortunately, I'm not really sure what to fix to resolve the core issue. Any help would be great!
