@JakeStevens thank you for pointing out the incorrect test. However, I cannot replicate your issue:

I believe bias=False causes a crash, or at least does for me in the converter

The test case passes without issues for me.

@JakeStevens , @MartinPavella , what neutron converter revision you used for testing? The tests here uses still the NeutronConverter_SDK_25.03.
Jake the crash in your case was with 25.06?

curious how did we not test this?

[MartinPavella]

We must have missed it in the rapid development during the early stages.
I have updated the tests again, to make sure the bias is (or is not) present.

I use 25.03.
