evolving rings stackable?

Just like Lilin's Ring?

It still wasn't a bug to begin with. Nexon eventually deemed it as such and fixed it later on. There's no indication that these rings aren't meant to be stacked until Nexon says otherwise. If Nexon never intended the rings to stack in the first place, then they would've fixed / adjusted the coding to fit the situation. That, in no way, was it in the player's bad / fault.

I mean I got 2 Lilin Rings during the time of when you could have all 3 equipped and when they changed it, I just shrug'd it off. It'll be the same way for these rings if Nexon doesn't change it until far later into the event.
