No, this problem is another, it stops a recursion too early...
to solve it go to line 242 of file RTInterface/RT.cpp
and change

Options.maxdepth =3D MAXDEPTH;

to something bigger (MAXDEPTH is defined as 5) like 8

please note that for every unit added the render time is doubled

We're working on those files... expect the first batch of changes =20
this evening, so don't work too heavy on this...
