New character stat

Hey fellow devs, I recently took a look at the character endpoint and I noticed something I hadn't noticed before. There is a stat in characterBase->stats that I do not remember seeing it before: STAT_OPTICS. It is lying there, along with STAT_DEFENSE, STAT_AGILITY, STAT_INTELLECT, STAT_LIGHT, etc. Its description says "Optical Zoom Multiplier", but it really doesn't belong here. It should belong to weapons. I wonder what it is... Also, it doesn't appear in the game, the website or the app. I've yet to see any other fan-made website show it too. Maybe it really is new... Any idea what this is?
