Hey @giovannifi, this should be fixed by https://github.com/modflowpy/flopy/pull/1510. To get around this until a new release you can work from the head of the develop branch.

for anyone else looking for a [convenient bash one liner to delete all caches](https://gist.github.com/w-bonelli/f84a18e985eb43175a7c0eecdb442d3f) in the meantime: ```shell gh actions-cache list | tail -n +5 | cut -f1 | xargs...

Hey @hansonmcoombs, I rebased your changes on top of `develop`. Looks like they will merge fine, although there's a [failing test case](https://github.com/modflowpy/flopy/actions/runs/3092228017/jobs/5003259600#step:8:2302) `test_plot.py::test_pathline_plot_xc` with an error reading a `.hed` file:...

@hansonmcoombs thanks for the help with the test, I updated the `flopy3_modpath6_example` notebook to reflect the same usage pattern. Also renamed/organized modpath-related tests, used `pytest-cases` to define reusable test data,...

a few more updates: - follow load/switch workspace/run model convention in `flopy3_modpath6_example` notebook - move MODPATH6 and MODPATH7 tests to proper (separate) files - trap `ImportError` when checking package availability...

This test case sees occasional failures which may be related: https://github.com/modflowpy/flopy/blob/9c42c373d73e886c9fba6b9a915f51508c002977/autotest/test_grid.py#L881 The number of cells per layer in the generated grid is sometimes off by 3.

Would it be best to close this and keep track of these in another location? I guess it sounds like they are not really flopy issues. I wondered if I...

With #2076 flopy should no longer produce invalid voronoi cell geometries, though mf6 does not yet have a corresponding trap to my knowledge.

Ignore my prior comments, they refer to unrelated issues. Reproduced in #2119

> I'm guessing that due to rounding errors the code is creating two vertices very close to one another rather than generating a single vertex. Confirmed @langevin-usgs' theory — flopy's...
