Pokémon GO developer Niantic has acknowledged a bug affecting surprise Zorua encounters tied to Tuesday's Shuppet Spotlight Hour, removing the encounter from Shuppet Spotlight Hours yet to occur while it works on a fix.
The bug caused Zorua that appeared during Shuppet Spotlight Hour in time zones including and prior to GMT+13 to retain the stats of the Pokémon whose form it originally took. Those stats include height, CP and attacks.
"Zorua already caught by Trainers will not be able to be Traded, sent to Pokémon HOME, or allowed in GO Battle League until this issue is resolved," Niantic tweeted Tuesday morning. "Please stay tuned for further details. We sincerely apologize for the inconvenience this has caused."
These Zorua surprise encounters won't happen in succeeding Shuppet Spotlight Hours, but the event will otherwise proceed as normal. Niantic has not yet publicized plans to offer new Zorua encounters to players in regions that did experience the bug.
