World Community Grid - View Thread - [Error] No atoms in the ligand

Saw this error popping up, just like in post 547966 (from 2017) and post 608154 (from 2019):

Out of 10,000 completed SCC1-tasks available in my Results, this was the only one with the error.
Inspection of 20 surrounding workunits (380115134 to 380115154) also didn't reveal any errors.

According to Seippel in post 417882:

The pdbqt line in the output give information about two pdbqt files being docked. The first is the ligand being docked and the second is the receptor site (which is why it's larger). The two numbers after each give information about the number of atoms and branches for each.
