So i was taking a schematic of my barns but i didn't want to copy the livestock. What i didn't realise was the remove option wouldn't just remove them from the save like i expected but actually deleted all my horses out of existence. Might want to put a warning label on that. Or even better adjust the save not the "real" world.

Yeah, it really changes the real world, since else it would be difficult to show you how things look like.
It's supposed to be a worldedit replacement.

i mean, delete does kinda mean delete.

I get what you're saying. And it's my fault as i was thinking of it as more of a schematica replacement than a world edit replacement.

I just didn't expect it to do that, i thought it was editing the save not the live copy. In schematic terms that would be very useful, you want a copy of something you're using but not necessarily the decorations/ furnishings... Remove them from the save and then go place a copy of the blank shell.

But at least you guys now know there are numpty's out here who are busy thinking 'woohoo, instaplace schematics!' and not realising that that means world edit is involved.
