>>49772681>>49772856>>49772868Original anon here, I don't have any more info than I started with (gf's been playing so I can't science it out myself) but the shininess roll definitely changed reloading the same save. I for sure know this because I saved at a certain spot halfway to the outbreak right after catching a shiny Chingling. If the shininess changes but the stats don't, that's weird but still possible. Apologies for not having more/better info and context.
