[Mesa-users] c13_pocket stop running during TACHeB

Thats telling you that you are hitting the limit of what mesa can do. You
would need to reduce the size of your nuclear network.

What does a kippenhan plot of your model show?

If you set list_net_reactions = .true. (to show the nuclear reactions in
your net) do you have any reactions with _to_ in the name (like rn14_to_n15
or ro16_to_o17)?
