I originally generated the ID/SID by pasting the seed into the Shiny PID section of Pandora's Box and verified the info after I managed to get the ID I wanted on my trainer card, but as far as double checking, no !!! comes up in the shiny column in RNG reporter, if that's what you mean, but I was under the impression that that wasn't necessary for shiny abused TIDs.Have you double checked if your ID/SID combination make your desired PID shiny?
Is that what you're referring to by double checking?
