[ccp4bb] ligand binding and crystal form

Hello all, I just solved a NCS-tetrameric (biological assembly is just a dimer) crystal structures with ligand soak (same plate - same conditions). No density for ligand is observed in the first map. In the 2nd, I have 1 ligand bound. In the 3rd, I have 2 ligands bound. Is there any reason for this

So the infamous Martin Shkreli is captivated by X-ray crystallography. https://www.ft.com/content/693ad306-9b6d-11e6-8f9b-70e3cabccfae QUOTE "He speaks of his love of Shakespeare and magical realist literature, and describes how he is captivated by science and medicine. “I’ve never done any art,
