I downloaded WorldEdit/SPC (Single Player Commands) and it worked fine! It was set for 1.6.2, so that's what I'm using for it. But when i try to use the 'wand' (//wand) it destroys the block when i try to mark the first block (using left click) where i want to replace the block (hopefully that's not confusing!) The right click works fine, but when i do //set [block], it sometimes works, but most of the time it either does it a layer wider or higher than i wanted it, or it places somewhere around 20000 blocks, like a huge rectangular prism. I don't know why it's not working, and i believe a downloaded it all correctly. I haven't tried all the other commands yet, but /i [item], /time day, /give [idcode] [quantity], all work. It's just the WorldEdit wand!! Please Help!!!
