bug: budgetfile.reverse() - unable to load w/ flopy

[pmt-usgs]

Bug Description

Using a transient mf6 structured grid model for testing PRT backwards tracking, the .reverse() on the .cbb creates a reversed file that is not the same size as the original and can't be loaded back in using flopy - flopy.utils.CellBudgetFile(os.path.join(prt_ws , budgetfile_bkwd_name)). Specifying single or double for precision doesn't affect the outcome and the error persists.

Also, potentially related, when trying to run the prt simulation an Unicode error is thrown.

System & versions
OS: Windows
Flopy version 3.9.2 and 3.10.0.dev2

Thank you for the help!

Hi @pmt-usgs thanks for reporting. Are you able to share your model? That will help us reproduce and fix. Or perhaps just the tdis if you cannot share the full model.

Thank you for the help @wpbonelli . I uploaded our model tdis that we've been trying to run a backwards prt simulation for a test well "pswell". Tried adding compressed model zip, but fails to upload. Let me know and I can email it to you.
