I can now reproduce Eric's results above
While generating some test data I have seen some strange model fitting results from mrds. Something to come back to when we look to improve the optimiser perhaps? Recording here so we have code to reproduce. It's strange because the data are generated from a half normal and it is not a particularly complex model. There is no association between distance and size.
