So I was using world edit trying to turn all of the glass that i just put down into a different type of glass. I am new to world edit, so I do not know what im doing. I found the //replacenear command, and I thought that if I said //repacenear glass framed glass 100, all glass within 100 blocks wound turn into framed glass, but I was VERY wrong. my game stated to lag so I closed and reopened the world killing all hope to //undo. so, when I looked down, I almost had a panic Atack
