I created a customized world and all I changed was the dungeon count from 7 (default) to 100 (max) then I created new world and found a lot of dungeons directly under where I spawned but there was nothing in the chest so I got a chest finder mod and created several new worlds like the other one different seeds though and found dungeons and there was nothing in them its easy to duplicate you don't need a specific world just create customized and change dungeon count from 7 to 100 and find a dungeon see if there is anything in it please help thanks
ps sorry for no punctuation but I didn't feel like putting commas and periods or anything
