I dont think you have to but for some updates especially in this few phase of development there is no way arround. Some things are just changed that would have to be changed for every safe individually. So its virtually impossible.
OK i´m not sure if this realy is a bug but coconuts cant swim, I placed my tree´s next to water and atleast one of them is allways falling into the water and I believe is not swiming because I never find it. Try your self maybe I´m just blind/stupid. Sry for my english.
