i think that they changed the golds quest into coins quest because of the new update : people can get golds by seeing their Tv ads
it is a new way to make moneys using the players : you see their ads, they got money !
this is how ads work (same when you see ads on Tv : Tv channels make money this way)
with golds quest , you got golds but they don't have money
the problem is : when i see their ads , i don't get the golds
so i stopped seeing their ads !
