[phenixbb] unrestrained refinement

I'm trying to do unrestrained refinement of a small molecule in phenix. I have done this many years ago, but it seems whatever I try, phenix.refine now complains about missing nonbonded energy type for all atoms.
The pdb file I supply has the following format (just one line)
HETATM 33 C81 UNK 1 3.117 14.425 18.765 1.00 1.45 C
I tried unchecking all references to geometry restraints in the GUI, setting wc and wu to 0
I also started from a default .eff file and set all references to restraints to either True of False (depending what they said).
I also tried the line from the phenix.refine documentation:
phenix.refine ../cif_in/mkt_a.ent ../data/181119/proc/137C3/XDS_17000.HKL strategy=individual_sites wc=0 refinement.input.symmetry_safety_check=warning refinement.input.xray_data.r_free_flags.generate=True
I'm using phenix v 1.14-3260 from an sbgrid environment.
Any pointers welcome.
