Re-importing from ZBrush claims "topology has changed"

in Technical Help (nuts n bolts)

I have a wierd issue with some models - in this case a hair model fit to a G2F figure that I wanted to sculpt into a slightly different profile - so I hot GoZ as normal ( export with deformations checked - export at current resolution unchecked - as always) into Zbrush make the change - hit GoZ ther as normal - it goes back to Daz - and then complains that the topology has changed and it will only bring it in as a new obj. I've seen this a time or 2 before but not sure why. All I'm doing in Zbrush is use the move tool to push the mesh around a bit - no topology changes.

Any ideas folks? Thanks

    So new information. Given that GoZ wasn't working, I shifted back to my old work flow and exported objs from daz - brought those into Zbrush manually - when I did so I got a message saying I had nonstandard ploygons and did I want to split them - when I did my shaping and exported the new obj - I used MorphLoader Pro to bring them in and that worked - so my guess it's GoZ's silent behind the scenes handling of these polys that is causing the topology changed issue. 

    Seem like a reasonable theory? Anybody else know about this or a less manual way around it? Hard to go back to the old work flow unless I have no other choice...

    If there is an n-gon that is being split, then yeah that would explain it, if Zbrush is automatically 'fixing' it.

    But which hair is it...because there shouldn't be 'non-standard' polygons on Studio items.

    Ahh,,,,not a Daz store hair.  In that case, yeah, there's a chance that an n-gon slipped in.  So if it isn't breaking when you export it as obj, then that's the way you'll have to go for this item.   That could also explain the problems I was having with an item I was trying to morph...I'll have to look at it again.

    Has this issue been resolved yet? I send a curtain object to Zbrush via GOZ. I make no changes, but when I GOZ back to Zbrush, daz claims the topology has changed.
