Robotics extension/position field reset to default after scene switch

[gotmachine]

From forum user Thatguywholikesionengines :

I'm using a docking port attached to a robotic piece on an SSTO for space reasons. I leave it extended while i go do other things with other craft for clearance issues. I come back, undock, and try to retract the robotic bit - But it's reset to zero extension. Extending the robotic piece just makes it stick out unnaturally far.

Something similar was reported on Discord. Unsure what could be causing this, needs investigation.

This bug also resets the action group.

I found a pretty severe bug with robotic drift fix. It resets the angle of locked robotic parts after a scene reload.

How to reproduce:

1. Put a robotic part on a vessel and launch it.
2. Change the angle of the robotic part and then lock it.
3. Reload the scene.

The angle of the locked robotic part will reset to its original position, but the part that's attached to the robotic part will not move with it, completely offsetting the hierarchy. Disabling the RoboticsDrift patch removes the issue.

Game version: 1.10.1

Reproducible on KSP 1.10, not on KSP 1.12
This is caused by differences in the stock robotics code in KSP versions below 1.12
Supporting older versions is frankly not worth it, so corrective action is to limit the patch to KSP 1.12+
