Not sure if this is a one-time thing, but it seems to be repeated. I've played a specific PVP duel with a friend, and he mutated one of my monsters using the Mutation card. I ended up getting an anubis with Paradox. However, his screen showed an anubis with immortality instead.
Does mutation not work properly with PVP right now? That's how it seems to me. I did have the same error with a spark with destroy in an earlier game, but it killed itself on my screen while it survived on his.
