Minimum voltage non-positive?

I changed the upper and lower cutoff voltages for Mohtat2020 to the more sensible 3.1 to 4.1V. But now I am getting this weird error,:
2022-11-17 10:31:19.330 - [WARNING] simulation.solve(622): Ignoring t_eval as solution times are specified by the experiment 2022-11-17 10:31:19.356 - [ERROR] callbacks.on_experiment_error(226): Simulation error: Events ['Minimum voltage'] are non-positive at initial conditions Traceback (most recent call last): File "nmcTest.py", line 25, in <module> sim.solve([0, 3600]) # normally 3600 File "/home/iviti/.local/lib/python3.8/site-packages/pybamm/simulation.py", line 746, in solve raise error File "/home/iviti/.local/lib/python3.8/site-packages/pybamm/simulation.py", line 724, in solve step_solution = solver.step( File "/home/iviti/.local/lib/python3.8/site-packages/pybamm/solvers/base_solver.py", line 1184, in step self._check_events_with_initial_conditions(t_eval, model, ext_and_inputs) File "/home/iviti/.local/lib/python3.8/site-packages/pybamm/solvers/base_solver.py", line 1063, in _check_events_with_initial_conditions raise pybamm.SolverError( pybamm.expression_tree.exceptions.SolverError: Events ['Minimum voltage'] are non-positive at initial conditions
any idea what it means?
