[Bug] File Operations -> Rename 2017-02-11 14:28:22 I frequently use the File Operations -> Rename function to batch rename albums into the file naming format I use throughout my library. When I recently updated foobar to the newest version 1.3.14 I started having a problem I've never had before through many different versions and my File name pattern has always been the same.File name pattern: %discnumber%.%tracknumber%. %title%Which would give me either01. Thunderstruckif there was no value in the Disc Number- or -1.01 Thunderstruck if there was a value in the Disc Number field.However, now, with the exact same File name pattern it is producing this[unnamed].01 ThunderstruckSo any file where the field is blank it fills in the %discnumber% variable with [unnamed]. I have attempted to clear the Disc Number field numerous times and there is definitely no value there.Now I obviously could create 2 separate file name patterns for whether I have a multi-disc album or not, but wanted to pose the question on this since it seems like an odd development after all these years and would be further odd to me if it was intentional so thought I better pose the question.
