I'm having a super specific error, which is puzzling me a little bit. I have caught the following Cleffa 100% legit on a German Pearl copy, like all the other Shinies I have radared for there, and for some reason, it and it alone throws up the error that it's a PID-Encounter mismatch, as well as the encounter type not matching up. The moment I move it over to Y with drag and drop, it shows up as illegal, while in the original savefile, there is no problem.
Edit to add: I have plopped the seed of the Cleffa into RNGReporter, and it does give me the exact PID of this Cleffa as a legal one for a Chained Shiny. It should be fine, all things considered.
