Create Aeronautics: Constraint Fix

ConstraintFix is a small companion mod that repairs a critical bug affecting airships and any structure containing rope_connector, rope, spring_connector and spring blocks from Create Aeronautics.

The Problem

When you copy a structure that contains ropes or springs — for example an airship whose balloon is connected to the hull by ropes, or landing gear attached with springs — and paste it using a Structure Block, a Create schematic, an NBT file loaded by another mod, or any template system, here's what happens:
The rope or spring looks intact (the knot/anchor texture and attachment points are visible)
But the rope or spring doesn't physically exist — you can't grab it, it doesn't swing, compress, or stretch, it has no physics
This happens because Create: Aeronautics saves rope and spring strand data using absolute world coordinates.

When the structure is pasted at a new location, those coordinates still point to the original build — the engine destroys the strand immediately, but the visual knot/anchor survives, giving the illusion of a working rope or spring.

The Fix

ConstraintFix intercepts rope and spring data at load time, detects that the connector was relocated (its saved anchor no longer matches its real position), strips the broken strand before the engine ever sees it, and automatically re-creates the rope or spring at the correct position on the next server tick.
Physics assembly (Sable sub-levels) is fully handled: the mod recognises world↔plot coordinate transfers and leaves them untouched, so assembled airships keep their ropes and springs through physics simulation.

Notes

Structures pasted before installing ConstraintFix can't be auto-repaired — re-paste them once with the mod installed.
