Infuriated players find Pokémon Go bug changes rare monsters to common beasts

Glitch causes random substitution of Poki(C)mon types at point of capture, turning high-level rarities into common-as-muck Rattata, Pidgey and Elkans for unlucky players

The latest bug to affect Niantic's smash-hit Poki(C)mon Go Android and iOS game has players swearing at their phones, as rare monsters become common beasts after capture, with Blastoises turning into Rattata and Ninetails into Elkans.

The glitch appears to have appeared in the last 48 hours following an update to the game that removed distance tracking and blocked third-party Poki(C)mon mapping services.
