Could you define big? I tried all your examples on a 174 * 94 * 146 selection with a volume of 2387976 blocks and everything worked perfectly. My copy command worked perfectly. //cut worked perfectly and //undo worked like expected.

Also, the client freezes because he receives so many blocks that it has to change. It's not something I can change easily.

I'm starting to think the problem is not in the plugin. Perhaps something with the architecture of the processor or the OS. We did once have a problem with ARM processors where the BLOCKFACE in the protocol changed to something else on a ARM processor. I'm using a x64 Windows 8.1 computer.
