Hi all,

I have been trying to implement rotation into a massive star, and I get
some weird error that I cannot wrap my head around.

As you can see from the movie, I stop a star near ZAMS (roughly model
number 900) and set an initial rotation according to the inlist I am
sharing with you.

Now what happens here is that my simulations during main sequence suddenly
get into an almost endless loop like the following:

Do you know what kind of problem I am facing right now and how to solve it?
