SERVER CRASHING WHEN SCHEMATIC PASTES

[JCLICKER]

So, I watched the tutorial on pasting schematics, and I'm getting the message in the chat that a bunch of blocks have been replaced, but I don't see anything, then the server crashes. When I get back on nothing happens and it works fine. Can anybody help? Should I get a different schematic?

It happens when alot of blocks are pasted into a server, I suggest removing world edit and using FastAsyncWorldEdit for a smooth paste.

Thanks!

Unfortunately, whenever I'm doing the command to get the schematic in it ends up not working on FAWE.
