Pistons + hinge + rotor + drills = instability, conflicts, and erratic behavior.

Hello.

I’ve been a fan since the early versions of SE1. I’ve played mostly in survival mode. Back then, scavenging for resources was absolutely vital. We came up with a mobile-arm drill design.

It worked quite well, within the game's physics limits.

I’ve replicated that same logic—see the attached photos.

But the whole assembly behaves quite erratically.

The hinge only works intermittently. It seems like you can only operate one element at a time; otherwise, conflicts or malfunctions occur.

I couldn't fully investigate the issue because the vehicle you see ended up making an absurd leap over a hundred meters into the air—with its piston arm spinning wildly—before crashing back down and causing the game to crash. Similar bugs used to happen in version 1 of the game whenever there was a conflict the PC couldn't resolve.

Anyway.

The point is, there seem to be behavioral inconsistencies when you combine multiple moving parts.

I particularly suspect the rotor. Piston + rotor + drills = weird behavioral or physics glitches.

I had started configuring the cockpit or seat interface buttons to control the vehicle's various components, but I noticed odd behavior there, too. One example that comes to mind is piston speed. In my setup, the extension or retraction speed varies even when the same value is entered in the interface. For instance, if I set it to "0.2," the piston moves differently depending on whether the value is positive or negative—at least in my extendable arm configuration. Another very "bizarre" bug observed: I managed to test the arm while it was extended close to its maximum reach. When I commanded the pistons to retract—to raise the drills and allow the arm to fold up—I was surprised to see the pistons retracting (with the speed fluctuations previously explained), while the rotor and drills "visually detached" from the pistons, drifting tens of meters away. So, visually, the pistons were retracted, yet the rotor and drills were 10–15 meters lower down, slowly moving upwards. Changing the speed made no difference. Eventually, the assembly smoothly reconnected; the "programming" link had held firm.

I want to emphasize that, for the time being, it remains impossible to mount drills on a rotor on a flying ship. A physical anomaly arises regarding the weight of the drills and rotor. It is as if the rotor amplifies the weight it is supporting at its tip. If you attach the same drills directly to the ship (without a rotor), it behaves normally and flies without issues; therefore, the problem isn't the weight itself, but rather how the system interprets it.

Thank you for your work.
