[mesa-users] Inlist issue

Hello Frank and everyone again,
I tried implementing the star_job parameters you recommended for rotation
and running a fresh model.
Rotation is definitely active and relaxed once the model reaches the MS.
However, I am still getting the
same issue.
Again, none of the controls below the mixing ones are recorded. That
includes mass loss, history and
profile formatting, etc.
I am including the new inlist file. If anybody has an idea what could be
causing this, I would appreciate
some guidance.
Thank you,
Yevgeni.
