Issue when running sim_deter_mosaic() in a targets pipeline

[jbarrere3]

The function sim_deter_mosaic(), located in the script dev_end.R, is yielding an error when used inside a targets pipeline (cannot coerce S4 to a double). Outside of the targets pipeline, the code is working fine.

After doing some debugging, it seems like the error comes from save_step_env() function, with a problem in the format in which DGE matrices are saved.
