Hey schullen if you would please make a ticket on our discord with logs or a screenshot of having a metagross an smod+ can help you get it backHi a pokemon from my team glitched away, relog doesent work.
It was only a metagros with 40% ivs on lvl 100. But it was my first one.
My ingame name ist SchulleN and i play on Pokesplash, maybe a mod can do something.
Best regards
