Some kind of edge case is apparently possible where the VCF evidence for a call cannot be found. I'm not entirely sure why that is, possibly to do with disentangling SNPs and indels, but this fixes it by defaulting to
None
when it cannot be found.The gnomonicus issue this fixes had a test case which has run without errors with this fix in place.
Possible TODO: Find the reason this happens. However, as this is affects 20/44,000 samples, it may not be worth the effort.
