The issue seems to be that the whole environment is duplicated inside the sim$data object from the loaded .rds sim. See attached. Top image is the loaded .rds environment, whilst...

PM_sim$load() is deprecated, and only returns the following message without any functionality: > `PM_sim$load()` was deprecated in Pmetrics 2.1.0. > ℹ Please use PM_sim$new() instead. ?PM_sim for details.

Thank you for the quick response. Reassuring re: PMtest - I will ignore for now. It was partly this that made me suspect a compilation issue. On re-running simulation this...

Thank you - I will send an email. To answer your questions - I did not use any covariates, nor augment the covariance matrix of the primary parameters estimates, which...

I have emailed you the model, but just to update, I have managed to get the simulator to run with this model and a manually specified poppar with mean parameter...

> possibly I think that the error is due to some combination of parameter values that causes the extra functions to fail. I don't think this is neccesarily the case....

As an update, I re-ran the model with significantly tighter margins, but the simulator still crashed with the same error. As I said, I'm able to run the simulator with...

To add further, the simulator works with a full covariance matrix provided I fixed the non-positive definite covariance matrix manually (negative eigenvalues very small (~-1e10^-8 or ^-9). Is this potentially...
