Ubisoft is investigating reports claiming that digital copies of Far Cry 4 have been rendered unplayable on Xbox One after the game was delisted from the Xbox Store.
"The team are actively investigating the issue this side," wrote Ubisoft community manager Mr_Shade, "however it's also worth contacting Xbox support - since it appears that the game has been removed from the Store - this has happened for some - please check if it's still available to you - if not, it 'could' be related to that, which MS are investigating too - however as I say, Ubisoft are looking into the issue as a matter of urgency."
It isn't yet clear which regions have been affected, why the game has been removed from the Xbox Store, or how widespread the issue may be.
At the time of writing, the game did not appear to be available to purchase digitally in the UK.
The issue, however, has raised questions over Microsoft's approach to licensing on Xbox One. Should a game be removed from the Xbox One Store in the future, for example, will it automatically be rendered unplayable to players who have previously purchased it?
This hasn't been the case in the past, of course, with games removed from the Xbox 360 Marketplace still playable to those who purchased them prior to their delisting.
