refineMesh + snappyHexMesh

I try to generate a mesh using "blockMesh" - "topoSet" - "refineMesh -dict" - "snappyHexMesh" (see Allmake script in the attached case). From the refinement step I expect better snapping quality without introducing too many cells with blockMesh. However this results in the error:
hexRef8 : Dumping cell as obj to "/temp-4/sb/calcs/wigley_fsi_short/OF/meshgen/cell_4053.obj" --> FOAM FATAL ERROR: cell 4053 of level 0 uses more than 8 points of equal or lower level Points so far:8(4467 4468 4498 4499 4963 4964 4994 4995) From function hexRef8::setRefinement(const labelList&, polyTopoChange&) in file polyTopoChange/polyTopoChange/hexRef8.C at line 3500. FOAM aborting
Looking forward to your suggestions
PS: I tried both OF 2.0 and 2.1.0
PPS: Due to the file size restriction I can't upload the stl - the wigley hull from the tutorial can be used

seems like this problem still persists in OF 2.2.0. I assume it appears when the topoSet is smaller than the domain.
Can someone somebody confirm this and or provide a solution?
For now I will use the order castellatedMesh - topoSet - refineMesh - snap.
