Sorry if this was suggested before, but I think objects created by yourself (provided that's actually a variable you used) should be able to be destroyed instantly, or at least a lot faster than they do. Along with that I think you should be able to use the destroy ability on items on the ground to clean up (say you leave blocks on the ground from destroying a tree stump). I know they disappear eventually but I'm a little OCD and like it nice a clean, lol
Thanks for readin'
