Bug while trading caused A-Vulpix to get mixed up

[Amine 171]

so uhm i was trading an alolan vulpix to a friend, who didn't want to post, they felt this will happen to others and will get reported anyway, but i wanted to make sure its posted :>

so we got this error a lot of times while trading, and after a bit they said vulpix was half alolan: its sprite is alolan but has drought as ability and ember (rip moonblast and freeze-dry) so yeah this is the result vulpix

EDIT: Apparently its not a bug, after testing it again, turns out trading pokemon while using rpg maker can cause this error, also that Vulix was made using rpg maker so that could be why it got messed up...I apologize, i thought it was a bug :[
