lol its eaisy make 2 rooms, in 1 room use the mixer filter and put filter in other room. Then put down the tiem u wana dupe (wont work with rares) and then it turns into mat, put mat in other room, go back to your other room witth nothing in it, dealeat ur other room with mixer and ur item in it, reload ur good room they shud be in center,rotate them, and another should apeair move it, keep doing this till it runs out
