If you are familiar with Wings you know what I mean
As far as I can see it all depends on the complexity of the UV mapping. If you set few UV zones, or if the texture one is using is relatively uniform, you won't ever spot the mistakes, if any.

Like I said earlier, if I clone vertices that are duplicated in the OBJ file the results speak for themselves:
This was your Wings3D OBJ barrage balloon imported into Iceberg01
