it sounds like you have lots of additional parameters and a very complex
and challenging system. There are many things that could be going wrong. I
might start with the water. Generating a new water model can be very
involved and not as simple as most small molecules. Why not adjust the
buffer distance to get the desired number of water molecules instead of
making a whole new water model (which is an entire project on its own)?
