Can you provide more information? Which item did you have?

A machine from the genetics mod

It happens when using the command on a server. Whenever I'm setting up scripts - I have to do it all in single player than copy it over to the multiplayer server. Its not really a large issue, just a bit peculiar. I think it also only happens for things in the Forge Dictionary - but I haven't done that command in a while.
