Niantic discontinued the use of Pidgeot in the Go Fighting League, after numerous complaints about a Pokémon glitch in Pokemon go.
The suspension applies to the ongoing Super Ball League rotation and will return to normal once the issue has been resolved. Niantic suspended the Flying guy because his players were reporting that their side of the match would freeze after their opponent’s Pidgeot attacked. This prevented them from attacking or interacting with the combat in any way.
However, this error does not appear all the time, and some players faced a Pidgeot and were able to complete the game without problems. For now, it looks like the problem isn’t just due to Pidgeot, but the Feather Dance movement. The move, which was released shortly before season eight of the Go Fighting League, is generally used before the freeze.
Because it was released earlier, some speculate that players who have not updated or restarted their app after launch are likely the ones experiencing the issue. Some even point out that the whole game fails after Feather Dance was used.
The issue should be resolved shortly, but until then, Pidgeot will not be usable in the Super Ball League.
