I've been doing it for completely different PIDs in different months, years, etc. and it still shows up wrong. I don't know of any factors that I could be "missing;" are there any common things people forget to do that would change its PIDRNG-determined characteristics? (I just found out that the genders didn't actually match, it was just coincidence that they were both male).
EDIT: Nevermind for now, I took PoJ's advice and reopened it, and I found results like normal. However, it may do like last time and give me a nonshiny offspring in spite of the !!! indicated in RNG Reporter. Thank you for your help so far.
