K. I use this code alot on WiFi. I use it to deseed xD
okay. Things I Descovered! (by myself )

1. When you lay stuff on the ground. sometimes you cant pick it up. To do this. you need everyone to be inside a building then you can pick it up.

EDIT:2. When you use this code. other people cant see the item you lay down. so you have to pick it up and drop/bury/plant it...

Thats I got by myself so far :P
Still using it.
