This is a bit of a frustrated rant about the inability to paste grids into the game. I've seen this issue for a while, but there doesn't seem to be a lot of info about it, or if others are experiencing the same issues.
It used to be, you could point the reticle at a block, then do ctrl-x to delete it (but still on the clipboard), and then ctrl-v to paste it back into the world, and the grid you are trying to paste would then rotate (more or less) around the block on which your reticle was pointed. As you can see in this video, this is no longer the case.
I have not yet tried to get this info to KSH, but I wanted to have a mechanism by which to illustrate the problem. "Picture is worth a thousand words." yes? In this case, I think the video illustrates the issue, and words are not entirely necessary.
