A lot of Oops! error with the new inbox released, when players click accept on the request and gifts they get :
Oops! There was a problem accepting the request. We’re working to resolve it!
and the gift items are gone
some players also said that the new gift box load cityville slow, and they can hardly mover around to neighbors + opening hotels
there’s no word from moderator on cityville forum about this error, so i guess you must let the gifts wasted~ when you get this error
