Hi Zac: Two suggestions. In the map statement, set silent = FALSE, hopefully that will give you more info, The second is to try what is suggested in the error message, " Try simplifying the model with the following argument: map = list(rho_o = factor(NA))". I don't know what rho_o does, but it might be a first step to figuring things out/ HTH, -Roy

I think the error is related to the optimiser in the TMB package but it is beyond my statistics/coding knowledge to track down the specific cause and solution. I would appreciate it if anyone knew some resources to assist with fixing this.
