Basically what the title says
On my server I have it where I delete "lots" so people can make their stuff, and so they don't have to have my trust either. But whenever I save it, and "Keep original ownership" and "save events" (or whatever those 2 say) are checked. When I go into single player and reopen the map, I find out that the brick ownership is made to be 100% mine, even though when I loaded it, the "original ownership" (or whatever it says) is checked, so it should have the original brick ownership, but it doesn't.
Any help would be appreciated
