Adv. Dupe thruster error

Whenever I attempt to spawn a contraption with the Advanced Duplicator tool, the contration will glitch, spawn, the thrusters will fly off with the message- “Error-Couldn’t spawn gmod_stool_thruster”.
I’ve tried getting different versions of Adv. Dupe, but to no avail. Help, anyone?

The contraption is broken because it’s using old thrusters before you could configure sound. Sorry :frown:
