I think it is a sphere refine problem. Just use the old real space refine.. sphere refine hates clashes , so before you try to fix something you need to delete any feature which will create one..\ I argue with Paul about the philosophy but he has the expertise! Eleanor On Wed, 2 Jun 2021 at

I have experienced the same issue with 0.9.5 for Mac. Most strikingly, this seems to occur randomly: some waters are refined as usual but other are shifted dozens of Å to stick to a carbon of the model. A similar effect is observed when refining solvents with the "x" key. On 1/6/21 21:45,

Hi Everyone, I also have observed the unusual behavior with waters not staying in the density after using the "r" key binding. In many cases, there aren't any egregious clashes that could be forcing the water out of the density. I tried changing the Lennard-Jones setting in the refine/regularize
