How do I serve those constructible parts in my stucks??? Like for certain parts of cooking machines you will have to collect parts from friends, and when they do send you, you accept them but then they go to your storage place along with your food! I try to click on the parts but it doesn't allow me to serve parts since they are not "food"!
So Is there anyway I could use them??? Or basically they are just useless n couldn't be use in any ways??????
