HollowingScream

Well whats weird about it is that my friends are using the exact same PKHeX and PKM file, but they dont get the same issue. I'm assuming it has something to do with the PC?

I still haven't been able to solve this issue with PKM files : /

Okay so whenever I try to add a event pokemon through PKM files, I get this error. Can any kind person please tell me whats going on?
