There are things that are part of a shard... like many things hidden away on GLs ... Seer items and such... Which IMO should NEVER be touched...
And then there are the dozen or so exploit statues that litter the road on GLs by Brit bank... the 100's of things of stew, watertroughs, carpet pieces, paintings, statues, Smith Hammers, etc... that are scattered to the 4 winds all over the lands along with parts of boats in the waters... and other garbage that litters the world that really do need to go... along with I know on GLs there are still probably 3 dozen items still stuck on the world from the destruction of Magincia... that have bars when you ctrl+shift... which could use removing... and stuff of that nature... I happen to like the two lanterns that are stuck in or near trees near Newcastle Township where I live... not far from Wrong... they have been there as long as I can remember... but stuff that blocks housing... garbage left from IDOCs need to go.
