I got a lot of information about Extra Bytes from you guys, To be honest.

So,It wont affect your save file or your pokemon?

When im editing my Poipole,I just realise that it also have extra bytes. (I deleted my Lurantis cause i worried that it will broke my save file at that time)

I......dont know how to describe it.Honestly

1.No,honestly. 2.Yes.UM data file. 3.Does it affect my data file if i have a pokemon with extra byte?

I have Lurantis with 17 Extra Byte. What does that mean?

Does it increase the pokemon size and height?

Wow,Thanks. Now i know the issue im facing and how to solve it Again,Thank You for the solution (i have checked your edited post)

The issue is, When i load my save, I started back in front of the entrance to Brooklet Hill(I have reached Ula Ula island before i edited it with PKhex) I use Checkpoint in my 3DS to load the save i edited(Restore selected save). I got my fennekin,but i lost a few of my progress (My 3ds has a SD card with PKMN games in it)

When the problem occurred,im afraid that my fennekin wasnt in the game,so i checked my box.After i know it make it into the game,i feel relieved. Also, Do you know the solution about the problem im facing? (About the save reset itself after i use PKhex on it)

Im new to this save editing stuff recently.But im having issue with my Pokemon Sun save file. I just added a shiny fennekin with an ability capsule into my save file yesterday and export it. I also use Checkpoint in order for it to work. But,when i open my game today,it loaded my last save before the water trial.[I have completed the trial before i use PKhex]. I went to PKMN center and check my box.And guess what?,The shiny fennekin is right there,with the Ability capsule i gave her I really confuse about this.Is there any solution for this problem? (Sorry IF my english is bad)
