Niantic has confirmed that Pokémon GO players will receive compensation due to a significant bug affecting the appearance rates of shiny Origin Forme Dialga and Palkia during the recent Ultra Unlock Raid Day event on August 10, 2025.
The bug impacted what was supposed to be boosted spawn rates of these shiny Legendary Pokémon, disappointing many players who participated in the event.
A statement from Niantic’s official support Twitter account acknowledged the issue, stating: “Trainers, we have identified an issue affecting the appearance rate for shiny Origin Forme Dialga and Origin Forme Palkia in Raid Battles during the Ultra Unlock Raid Day.
We are planning compensation for affected Trainers and will share more details soon.” Although the exact form of compensation has not yet been announced, Niantic has assured players they will receive something to make up for the diminished shiny encounter rates.
The Ultra Unlock Raid Day was part of Pokémon GO Fest’s global challenge series, which rewarded players for completing various goals.
This particular Raid Day featured the Origin Forme versions of Dialga and Palkia, with shiny variants expected to appear at higher rates to celebrate the event.

Many players noted unusually low shiny encounters despite participating in numerous raids, leading to widespread criticism and disappointment.
Looking ahead, Pokémon GO will host its Fest “Max Finale” event starting August 18 through August 23, 2025, centered around the introduction of Eternatus and the new Max Battle challenge featuring Eternamax Eternatus. Niantic is also preparing September’s Community Day, highlighting the Fairy-type Flabébé with distinct regional forms and an increased shiny chance on September 14.
Players affected by the Raid Day bug await further details from Niantic on the planned compensation. Meanwhile, the community is eager for the upcoming events to continue the excitement and momentum following this summer of major Pokémon GO activities.
