Inconsistent confidence intervals csolnp / npsol - plots

Should I expect confidence intervals to be working for csolnp at the moment?
I ran a number of fits, generating random start values, using the same data. The following plots of four of the model parameters and confidence intervals show quite some inconsistency / strangeness, I think. Although the likelihood varied from fit to fit, the differences were very slight. Estimates were all from good fits (no code reds / blues).
The x axis of the plot is both parameter (1-4) and within each parameter section is iteration 1-20. scaled likelihood values 1-20 are in the top section of plot.

these data files contain lists of the fit objects from the 20 iterations, in case they are of interest.

Based on what you're
Based on what you're reporting here, no, it doesn't look like confidence intervals are working properly with CSOLNP.
EDIT: Have you tried the new (third) beta (or built from the head of the repository recently)?

Built openmx again yesterday.
Built openmx again yesterday. Ran a similar model, got similar results.

Hmm. OK. Bummer. Thanks
Hmm. OK. Bummer. Thanks for checking, though.
