Drop Module Behavior swap? (Index v Specters)

[Zelier]

Recently (ish) ..probably right before the holidays, the group I played with and I noticed that some drop behaviors changed. Indexes previously dropped red modules that were "unknown" until the end of the match. The Silver Grove Specters would originally drop red modules that were identified upon pickup. At some point this behavior completely swapped. I was wondering if this was a deliberate, permanent change or something a little more incidental. Certainly not the end of the world either way, but I did much prefer the previous iteration. 

Wondering if someone knows any more about this?
Or if you've noticed the same behaviors, and can help me narrow a window, because I admittedly neither Apothic hunt or Index with any sort of regularity that I could determine when exactly it happened.
