Hi,
I think the Worldedit GUI was also made for those users who like me play with their children a few hours in the evening. So many players like me play minetest as it is. They do not know all the chat commands to work with eg worldedit.
The "set nodes" search option provides "Cobblestone" by default, and simple players think that the displayed "Cobblestone" node is what Minetest provides by default. Maybe I'm wrong?
I prepared a 3x11 surface made of cobblestone + stone with WE GUI. It worked. But when I
copied it 3 nodes in "look direction",
the problem recurred:
the first selected line has staggered once the command has been launched (see image below)See also the white line of the center of the "street" mod....
both when generating a surface and/or when copying / pasting, this problem may occur...
Thanks, and be patient please.....
