Sorry if this seems confusing: So, one day I was on Pokémon HOME and I traded a person for their shiny Lugia. It was from Unova and had the alola champion ribbon. Then, I put the Lugia into my Sword save file once the crown tundra came out. I battled with it and did a whole bunch of stuff with it. Next thing I know, when Nurse Joy heals my Lugia, it freezes it’s little section and doesn’t move its wings, and that concerns me. The game itself doesn’t freeze, however. Most Pokémon will move when they are being healed by nurse Joy in that little cutscene. Why? Is it Illegal? Here are the stats of it. They are pretty detailed because I just want a direct answer. Just don’t pay attention to what you don’t need to know.
(Dream ball) Lugia Lv76 (Italian) (it came as level 67)
Dynamax level: 4 ( I gave it the dynamax level)
Sp. Atk: 165
Nature: Bold, it “likes to thrash about!”
