[freeside-users] Can't call method "invnum_date_pretty"

[Timothy Butkiewicz]

Getting the following error. Far as I can tell it has to do with a date
in a field or a missing reference, but in reviewing the database we
can't locate the record causing the problem. Any leads?

error:   	Can't call method "invnum_date_pretty" on an undefined
