Fossil BAMM - preservationModel problem

[Laura van Holstein]

Hi Dan, 

First of all a massive thank you for BAMM & all the helpful documentation! 

Just wondering if there is something I'm doing wrong - I've got a (small) phylogeny with fossils for which I want to run pretty much the same analyses as Mitchell et al. (2019) (https://doi.org/10.1093/sysbio/syy035). 

However, I get the following error: 

ERROR: One or more parameters from the control file does not correspond to valid model parameters. Make sure that you are running the correct version of BAMM or check that the following parameters are spelled correctly:

             preservationModel

I'm running BAMM 2.5 & am using the standard "preservationModel   =   one_rate" in my control file. 

Any help would be appreciated! 

Many thanks, 

Laura
