Since the Zygarde cells are seemingly going to become more important I feel like I should ask this now.
There's currently 1 Zygarde cell that is completely missable, in goldenwood park during specifically phase 2 of the restoration quest. There's another cell available in the park after you complete the quest which leads me to believe this might be an error, but as of right now they are two separate cells, and if you don't grab the phase 2 one you can't get it anymore.
Will this cell be possible to obtain another way and/or will there be another cell elsewhere so that anyone who missed this one can still obtain the full 150 later? It would suck to miss out on something important like this just because you completed the restoration quest before double checking.
