[mesa-users] bad angular_momentum_j

I'm currently working on adapting additional magnetic braking terms into
MESA using the run_binary_extras.f file. I'm currently running into an
issue where the amount of angular momentum being removed is too great in a
single timestep and causing the simulation to break. Looking at the code it
seems like the MESA binary evolution dies immediately if the angular
momentum loss is too great instead of retrying with a smaller timestep. Is
there a way to get MESA to retry with a smaller timestep when it encounters
this issue?
