Can no longer classify invalid HGVS (one we can't resolve)

The classifications page has a HGVS entry text box, where you can enter HGVS that fails (eg NM_007300.4:c.2902_2959inv) and classify against it.

This was done by passing the "classify" field to the search, which has special case.

I think this was broken in the conversion to crispy forms - it no longer renders hidden fields so the "classify" hidden field is not passed to the search form anymore

Start at the classifications page's HGVS entry text box and follow how it submits to the search form. Check the crispy forms conversion and the special-case handling of the "classify" field; done means an otherwise unresolvable HGVS such as NM_007300.4:c.2902_2959inv can be classified successfully.
