Modpack version
0.4.14

Describe the bug
So I have a veggie farm with the piston extender in create and harvesters and it was working fine, but I updated it using Gantry carriage to move it and when I connected the gantry to the windmill it killed the e6 server. When the server was up again the gantry carriage, the chassis and the harvesters where gone. I assembled it again in a different set up and when I connected the contraption with the gantry shaft to the windmill it crashed again. It is the first time I use the gantry in a contraption.

Likely lithium, which is only on the official server.

Lithium? From Mekanism? I haven't got any.

Hes talking about the performance mod lithium XD
It causes some issues here and there

This is being worked on, but is invalid for the modpack :)
