Both errors are caused to in_batches using id instead of hid

  Activity::History Pluck (1.1ms)  SELECT "history"."activities"."id" FROM "history"."activities" ORDER BY "history"."activities"."id" ASC LIMIT $1  [["LIMIT", 5]]

Activity.in_batches(of: 5).map(&:count).uniq.all? { |c| c <= 5 }
=> true
Activity.history.in_batches(of: 5).map(&:count).uniq.all? { |c| c <= 5 }
=> false
