Hey! I'm replying anyway, because the RNG does indeed stick sometimes, on White at least. I haven't done it on Black myself, but I will sometime. And the RNG Reporter stuff you mentioned is called Researcher. What it does is research your seed essentially, and the numbers and stuff at top right are calculations to make the results window show what you want to see, in this case it was natures and characteristics. And we had to use that because the main window still has a bugged characteristics checker.
Heh, I was waiting for your post (or a VM), I was seeing the crazyness the current suspect OU voters are doing now. Let me clone the Eevee first (it is quick), then I'll VM you again. Your FCs are those in your post in the thread, right?
