What spawn code do I need to use to spawn pine sapling in multiplayer? On some website I saw something like 17-1 (17 for the sapling, and 1 for pine since 1 is the type of a sapling).. But when I try spawning 17-1, i get the "There's no item with id 17-1" message. Oh and I tried googleing, but can't find the code anywhere.. Hints? Thank you.
