Problem saving HB using Colibri (-99 error)

Hi all,
I’m trying to use Colibri with HB but one and sometimes two of the 9 simulation results are recorded as -99 in the excel file. The rest of the results look good. Just wondering if any one knows what the reason is?

Many thanks,

What do you get when you run the study without Colibri?

I get an actual sDA value, e.g. 38.
