!self$finished is not TRUE error when running many_models()

[adammedcalf-ww]

Hi,

I'm getting this error when running many_models with default options:

"Error in pb_tick(self, private, len, tokens) : !self$finished is not TRUE"

I believe it's something to do with the processing output to the screen, as if you use the verbose = FALSE option it doesn't occur and the models are correctly created.

Thanks,

Adam
