I am experiencing problems with accepts_nested_attributes_for as well in my Rails 5 beta 3 app and seems like it is buggy. Ideally, a bug report should be submitted, but we didn't have time to do it properly. We have the following setup:

accepts_nested_attributes_for :attachments, allow_destroy: true

Eventually, we had to monkey-patch the method inside the model like this:

  def attachments_attributes=(attributes)
    attributes.reject! do |_attachment|  
      if _attachment = Attachment.find(_attachment['id'])
        if _attachment.drop_id.nil?
          attachments << _attachment
          next true
        end
      end
      next false
    end
    # assign_nested_attributes_for_collection_association(:attachments, attributes)
  end

The only thing is that the last (commented-out line) with assign_nested_attributes_for_collection_association has some issues, but hopefully this will provide you an idea how this can be fixed.
