copy and paste glitch

i found this glitch to be one of the worst i'am not sure when it happens but if you build something on your world and then you quit that world then go to somebodys world it might copy the stuff you just built from your world on to there world. it happend to me twice. once i made a big track quit and went to somebodys world and it copied on there world. srry if you don't understand what i was trying to say

Its not a glitch, its a design choise, but I know people dont like it. Will add a copyright checkbox, didnt make it this time though.

Yes that also has happened to me . I always save my world to a usb stick after I'm finished building than I f I'm gonna join other players game I always back up my world first just in case. Its very helpfull . Just go to storage and copy the lootfest file not the lootfestlivedesign file.
