Description

I have noticed that physics warp weakens springs relative to gravity. It is most noticeable when everything is static and all the forces ought to balance.

Example: Build and launch the following from the VAB: Stayputnik at the top, X200-32, docked pair of Clamp-O-Trons, another X200-32. Wait for it to settle and then physics warp - the upper Clamp-O-Tron will sink into the lower one.

I suspect that "flapping wings" on a plane is related to this.

The example is static, so physics step size shouldn't be an issue (at x1 the net force is zero; at x2 the net force should be zero for 2 time units). So is this a bug, or is it a deliberate change to prevent explosions during physics warp?

That's how the physics engine works and there's a warning message when Phys warp is activated for the first time letting the player know this kind of issue can happen.
