It appears that the Deus Ex: Mankind Divided publisher Square Enix have some explaining to do, along with developers Eidos Montreal, after the release of the new DLC.
Apparently, players cannot download pre-order bonuses to more than one save, but that is not the only thing that has angered casual and faithful Deus Ex players alike.
This means that items cannot be retrieved again in future playthroughs because the developers have decided to catalogue these items as consumables.
Pre-order bonuses are now ‘single-use only’, meaning that players can access their pre-order bonus content, but are only allowed to transfer said item into one save.
