You are using different restraint files for the two runs, so of course the
energies will differ. Take Ross Walker's advice, and try *short* runs with
ntpr=1. That is always a good idea when you results you don't understand.
Only printing every 20 steps makes debugging or understanding what is going on
very difficult.
