Description

@mjoyceGR and I noticed that a 1Msun evolution track (r230501) is a bit bumpy on the HR diagram (Lum vs Teff) around the first acent RGB, with `use_Ledoux_criterion = .true.`. Here I attached the inlist to reproduce this track. For comparision, with `use_Ledoux_criterion = .false.` the track is much smoother. It would be great to gather some insights on this issue and improve it in future releases.
