Thanks for the heads-up!

Foresight's description states 'Enables a Ghost-type to be hit by Normal- and Fighting-type attacks. This also enables evasive targets to be hit.' When using my Sentret against Gastly at the Graveyard near Vermillion, I've been unable to use Fury Swipes nor Quick Attack after using Foresight, it just tells me 'It's completely ineffective!' And yes, I'm certain that I've used Foresight, I've tried this multiple times.

Disconnect your controller, or go to 'Options' > 'Key Binding' > turn off 'Allow Controller'
