@enomotodev @donquxiote someone can review this pr?

In the meantime, if any one stumbles upon this, you can remove the select from the query that the gem adds with unscope.

class Stuff < ApplicationRecord
  acts_as_taggable

  has_many :things
end

class Thing < ApplicationRecord
  belongs_to :stuff
end

Thing.where(stuff: Stuff.tagged_with(["foo", "bar"], any: true).unscope(:select))
