ERROR openfe/tests/protocols/test_openmm_equil_rfe_protocols.py::test_tip4p_check_vsite_parameters - ValueError: No registered small molecule template generators could load force field 'openff-2.1.1'

we can't use openff-toolkit =0.13.x

[mikemhenry]

Well at least not with openff-2.1.1 ff, so since that is the only error, it might work with an older ff version

I'm really not sure how 0.13 handles things like NAGL - it might be best not to go below 0.14 if we can avoid it.
