ad_hoc
(they/them)
That doesn't play nice with spells like Locate Object, where even though the target is technically "self" there's still some sort of magical effect that pings the object(s), which can be behind all sorts of barriers and obstructions.
To be consistent with the no-barriers rule Locate Object should only find objects you could in theory already see, assuming lighting conditions allowed, and this would render the spell close to useless.
It would be very good to help you find your glasses.
