Hi

In 1.4.106 I get the following Assertion Error when I use kicked maps (refinement.ordered_solvent.use_kick_maps=True) in the solvent update section:

Traceback (most recent call last):

AssertionError

Running from the same .def file w/o kicked maps works fine. Let me know if you need more info to debug this.

Cheers,
