Shiny Celebi PID reroll problem (Card # 0108 - Mystery Gift)

[alanrius]

Hi people, (sorry for bad english) I have this problem when I try to reroll PID on this shiny celebi (event from the movie 2020). I tried to reroll a lot but I get this error everytime, what I'm doing wrong? (I can change without problems: EC, OT by language of the event, date, etc).
I'm using the PKHEX's MG database and I think that it doesn't have fixed PID (like the Shiny Zeraora).
I've tried rerolling with normal shiny and on square shiny

Yes, Celebi does have a fixed PID, as do other shiny gen 8 events (Korean Amoonguss). The only way it's legal is to have that fixed PID, earlier versions of PKHeX didn't account for this. What do you need a rerolled PID for?

Furthermove, all event shinies are displayed as Square Shiny.
So you won't be able to change them to Star Shiny, even if the PID could be rerolled.

Great, thanks! I dind't know that (I was trying to reroll so I can have a different PID Celebi, as I did that on old events. Now I know it's useless). I thoght Zeraora was an exception .
