Please forgive my poor english capability
So you mean Tapu series, Metagross and Tyranitar don't have a fixed PID, and ash-greninja, eevee and Zamazenta have a fixed PID. right?
And please answer my one more question.
At event gallery, it was said that the PID of shny Dialga, Palkia and Giratina have a random PID. (BW, BW2)
But when I reroll their PID with PKHEX, it says that the PID was mismatched.
I rerolled PID with other shiny event pokemon at BW2, but the result was same.
Is this a bug of PKHEX?
