Today both the Unit 13 demo and Facebook apps were pulled from the PlayStation Store.
A number of Vita Facebookers have received the error code “NP-13144-3?” denying them access to the service. Sony has attributed this to something on Facebook’s end. The app has been pulled until this has been ironed out, with “no timescale” for when the service will return.
The Unit 13 demo was also pulled from the PlayStation Store, due to possible problems causing Vita’s to crash. Sony removed the demo from the PlayStation store with the European twitter account stating “You may have noticed that the Unit 13 demo has been removed from PS Store. We are working to reinstate it as soon as possible.”
Other issues with the demo include audio cutting out and other applications refusing to open after quitting Unit 13. At this present time the demo is still available in the United States, only being removed from the European Store.
