it makes item frames leeds and more move several blocks away

it makes lots of block add ons or other things appear far away and the ones that you can see do nothing and the place where you put it also does not do anything like if you try and destroy them put if you break the block or place a new block in front of the block where it is supposed to be (only for things like item frames) then it makes the item there where it is supposed to be (dropped items do not have a effect on this glitch) pls fix it things like adventure maps do not work or are broken now now I don't know if you know this already but it's been 2 weeks and it is not fixed
