Mech mod crashes

[roflcopters270]

When ever i try to open the mech invintory it crashes or craft a mech it says I don't have en engine when I do and when I push the craft button it crashes wtf is going on?!

The engine needed isn't called an engine, it's a basic CPU for the proto titan and advanced cpu for the alpha titan. I got the proto one to craft, and could open it's inventory, but couldn't make it turn, there's a bug in the code. You can go forward and back, and side to side, but you can't make it face a different direction.
