Power Grid wires break / desync when moved by Aeronautics Physics Assembler

[Daxfgr]

Description

Describe the bug
When using Create Aeronautics' Physics Assembler on a structure containing both Create blocks and Create: Power Grid blocks connected by a wire, activating gravity/physics causes a desync:

• Create blocks move correctly
• One Power Grid block moves correctly
• The other Power Grid block stays frozen/floating in its original position
• The wire connecting the two Power Grid blocks breaks and disappears

To Reproduce

1. Build a structure with a Create Aeronautics Physics Assembler
2. Include Create blocks and at least two Power Grid blocks connected by a wire
3. Activate gravity/physics on the assembled structure
4. Observe: one Power Grid block does not move with the rest of the structure, and the connecting wire is destroyed

Log excerpt
[Server thread/DEBUG] [mixin/]: Mixing sable.SubLevelAssemblerMixin from powergrid.mixins.json into dev.ryanhcode.sable.api.SubLevelAssemblyHelper
[Server thread/DEBUG] [mixin/]: powergrid.mixins.json:sable.SubLevelAssemblerMixin from mod powergrid->@Inject::powerGrid$moveWireStuff(...)
[Render thread/ERROR] [dev.ryanhcode.sable.Sable/]: Received a sub-level movement packet for a non-existent sub-level

This suggests a timing/race condition: Power Grid's moveWireStuff mixin injection fires before Sable finishes initializing the sub-level for the assembled structure.

Environment

• Minecraft: 1.21.1
• NeoForge: 21.1.247
• Sable: 2.0.3
• Create: Power Grid: 0.5.5.1
• Create: 6.0.10
• Create Aeronautics: 1.3.0

Expected behavior
All blocks (including Power Grid blocks and wires) should move together with the rest of the assembled structure without desyncing or breaking.
