“Effect Requirement not satisfied” is displayed for all cancelled tool attachments because a selection for attachment is an effect requirement for PlayPokemonTool. As for grabbing it with the move, when was it displayed?

This error popped up after clicking Cancel, which is the only way to opt to bring Cessation Crystal to hand. Note that it doesn’t affect gameplay, just seems like an unnecessary prompt in general.
