# Issue with ActiveRecord#includes
Checked with the latest rails versions
- 5.2.4.4
- 6.1.1
## Models
## The Problem
- `c_type_xs` is a scoped has_many in A, through Bs (source Cs)
- `ds` is a distinct has_many in A, through Cs
Under this condition, if you switch around the orders in includes, you get different results.
### spec/models/a_spec.rb
```rb
it { expect(A.includes(:c_type_xs, :ds).find(subject.id).c_type_xs.size).to eq 1 }
it("if you switch includes around, you get different results") do
expect(A.includes(:ds, :c_type_xs).find(subject.id).c_type_xs.size).to eq 1
end
```
## How to reproduce
Just run the docker, and it will run rspec automatically.
```
$ git clone && cd activerecord-includes
$ docker-compose run --rm rails-5.2.x
$ docker-compose run --rm rails-6.1.x
```
