Got KER? check twinboar please

[Kyrt Malthorn]

If anyone else has Kerbal Engineer, head into the VAB and from a blank slate, add a single Twinboar engine.  My KER readout shows this engine with no other parts what so ever, has a net torque of 0.01.

What the?  That shouldn't happen.  Did SQUAD offset the thrust by accident? Is KER reading it wrong? I wonder if Mechjeb says anything different.

I've seen engines do that before and never figured out why. Sometimes just detaching the part, leaving the VAB, then going back in has solved it. I'm not sure if it's a KER bug or Squad bug

Yeah sometimes you get torque with perfectly symmetric designs. I know that some models are off-centered (Mainsail) but I'm not aware that the "placement" of engines or other parts can be off-centered as well.

It's probably something to do with KER, and I'd bet on floating-point errors: 0.01kNm of torque is really small and that Boar is very powerful so it could happen that KER doesn't round the values to 0 properly.

One should check with other mods to see if the same happens (RCS build aid, MJ...).
