Allagan Weapon Sheath/Unsheath Sounds

[Veezora]

Hello, I wasn't quite sure where to ask this, but sometime last night I suddenly realized that my Replica Allagan Rod's sheath and unsheath sounds had changed from a normal staff unsheath sound to something a bit more clunky and mechanical sounding. Not a complaint exactly, I just wondered whether anyone else noticed this with an Allagan weapon, or whether it's a bug.

A few weapons do have custom sheathing sounds, the high allagan and moogle ones come to mind immediately. I don't remember if my old allagan ones do or not but I would not be surprised if they did.
