Missing 1 zygarde cell :(

[Jbkdude1]

Are there any commonly missed cells or time locked ones that the seribii guide has wrong? I really don't want to go through every single location again.

I myself am missing 2 cells and after going through every location a couple times, couldn't find what cells I was missing at all.

I don't know any other benefits of having all 100 cells other than the power construct form so an alternative you could do is trade a pokemon for a Zygarde (for example, I got a 10% form one off Wonder Trade. I was able to have a power construct Zygarde by separating that one.)

I found about 75-80 of the cells before I lost track of which ones I had collected (because I had skipped over some of the time sensitive ones). I didn't want to revisit everywhere to see what I had missed, so in the end I just used Pokebank to transfer my Zyrgade from Omega Ruby (originally caught in Y). I had become quite attached to that one, so instead of disassembling it, I disassembled my 50% Moon version, added those cells to my Y/OR version which gave me a 100% version with power construct, and had enough cells left over to assemble a 10% form to keep separately in my living Dex.

Felt slightly like cheating, but I am happy with the result lol

I followed some "walkthroughs" for it.
I had to redo it a couple of times to get every single one because for some reason I kept on missing one or two.
Best thing to do is really just go over it a couple of times
