Forza Horizon: Game was again available in the store in the store

Is Microsoft plans to return the first part of the Forza Horizon series to the Microsoft Store? At the weekend, Forza Horizon was surprisingly available for a short time in the store for sale. And that shouldn't be that way.

Because, Microsoft removed the game in October 2016. This was probably the case for license reasons and also because with Forza Horizon 3 the latest part was before the publication.

Why the first part of the open world racing game series was available again for sale cannot be answered at the moment. Maybe it was just a mistake. Or there will soon be an announcement on the part of Microsoft.
