Kerbal Space Program

Description: KAL-1000 Controller can give engines negative or excessive thrust

Steps to Replicate:
1) Make a craft with some form of control, an engine (and fuel tank if required), and a KAL-1000 controller
2) Under action groups, assign thrust limit to the controller
3) Drag nodes until the curve goes outside the box, above for excessive thrust, below for negative
4) Launch the craft and make sure that the KAL-1000 controller is in a region that goes outside the allotted space

Expected: Engine will stop thrusting/reach max thrust with curve goes below or above the editor respectively

Result/Observed: Engine will either produce more thrust than it is normally capable of, 0 but generate fuel, or negative thrust with no other effects.
