XBB.1 misclassified as XBB in Singapore in samples after 2022-10-10 #49

Hi

A recent batch of genomes from Singapore has been classified as XBB even though they appear to have the lineage defining variants S:G252V and ORF8:G8*:

I believe it's scorpio related, as Nextclade classifies most of them correctly:

I don't have access to the raw genomes - possibly also brought about by some contamination or other sequencing issue - but worth keeping an eye on, because at face value it appears as if XBB is replacing XBB.1.
