Reports of Street Fighter V users unable to purchase the new Temple Hideout stage–part of the large update SFV received yesterday–started circulating last night, shortly after the content launched. It seems now that the stage has been outright removed from Steam and the in-game Shop; players that have already purchased the stage are offering mixed reports of it being still selectable in-game, or not. [I have personally verified on PlayStation 4 that the stage is playable, but no longer appears in the Shop listings. – Editor]
