Nobody has this problem?

Hi, First of all, really nice to see that Revit Type groups and Revit Instance groups are now combined into one Pset in IFC's from Revit. This is really helpful when looking up parameters in IFC and not having to choose from type or instance Psets. But I recently found an issue on this where it doesn't work for all objects. See attatched Excel ITO file from Solibri. This is an IFC file from Revit 2018.3 exported with IFC Exporter 18.4.0.0. Is this a know issue? I couldn't find any topics about this....

please keep us updated, this issue is the absolute deal-breaker for IFC and open collaboration (my opinion)

So.. How can we rely on IFC if the IfcGuid keeps changing?? THIS IS A HUGE PROBLEM!! I really want to adopt all the standardisation made bij buildingSMART, but we need to rely on the unique GUID's stay the same after multiple IFC exports from Revit AND other software. When can we expect this to be fixed??!

So, Version 18.4.0, 6/25/2018 is out. In the 'Export Bug Fixes' section, I read the following: Restore proper GUID for some door, windows, and property sets. So does this mean the 'Changing GUID problem' is now fixed? And if yes, will it be fixed as well for the 2016/2017 versions? fingers crossed..
