ONIOM calc not passing # of unpaired electrons

[tmachonkin]

I have been trying to set up and run ONION geometry-optimization calcs, and have been running into some problems.

If I run an open-shell system through xTB, it ignores my attempts to specify the number of unpaired electrons. I tried it using the input file ($spin 3) and I tried it in the command line (--uhf 3), and both times in the output file it gave

  :  unpaired electrons                  0          :
  ...................................................

What am I doing wrong? How do I get it to run with the correct number of unpaired electrons?
