crash Whenever I try to use the .pf save command with the Pantograph from the QP Chisel Tools mod, I crash.

[GeneralMcShooty]

Hello. I am in the Age of Seraphs multiplayer server and have recently tried using the Pantograph from the QP's Chisel Tools mod. In particular, I tried using the .pf save command. I've talked to someone else on the server, and they say they can use the command just fine. Can somebody help?
 I'm currently using v1.20.12
