That is unexpected, thanks for reporting.

Ah, this one is a perfect example of https://github.com/unisonweb/unison/pull/4962#discussion_r1617594164

dependents returns References as its numbered args (but prints based on the HashQualified Name). Then delete.term expects a name of some sort, which Reference doesn’t have, so it fails even though we can see the name we want right there.
