I should have said that I am getting corrupted restart files for the explicit solvent simulations, due to what I think is overflow (****** where values should be). Nothing unusual is happening to my structure, its definitely not blowing up. What I also dont understand is that the restart file should be the last set of coordinates from my trajectory, but my trajectory file does not appear to be corrupted.
