Polygroups being destroyed after import and step up in subdivision

I ran into a case where I had to import in my model at the lowest subdivision level as an obj, it had polygroups and would import them in at the lowest sub d level. Once I stepped up in sub division levels the poplygroups were destroyed and there was only one polygroup for the entire model. This happened several times.

To fix this I used some of the poly grouping features, such as group by “UV Groups.” Then I imported in my lowest sub d level and everything worked.

No resolution on this yet. Has anyone else seen this issue?

Hey Nick,
I am getting the same behavior and/or the polygroups remaining intact but adding more polys to the group after going up and down in the subdivisions. Workaround for now is to save out my initial poly groups as masks so I can load them back up later via Polygroups>From Masking. Would be nice if the polygroups would just stay intact. Don’t have time just yet to try and repro what might be breaking them.
