[NPE] Create 6.0.10 ContraptionColliderMixin causes NullPointerException in ContinuousOBBCollider (mf.axis is null)

[RyannnnS]

Describe the Bug

With Sable 1.2.2 (and sablecompanion + sablephysicscompat) installed alongside Create 6.0.10
and several Create addons (Aeronautics, Big Cannons, Diesel Generators, Threaded Trains etc.),
the game crashes with a NullPointerException when a contraption ticks / collides.

Error: Cannot read field "x" because "mf.axis" is null
in ContinuousOBBCollider.collideMany, triggered via Sable's ContraptionColliderMixin.

Steps to Reproduce

1. Install NeoForge 21.1.232 + Minecraft 1.21.1
2. Add Create 6.0.10 + Sable 1.2.2 + sablecompanion + sablephysicscompat
3. Add Create addons (Aeronautics, Big Cannons, etc.)
4. Start singleplayer world with an active contraption (train / aircraft / cannon carriage)
5. Crash occurs on server tick loop

Expected Behavior

Contraption collision works normally without NPE.

Actual Behavior

Server tick loop crashes with NullPointerException from Sable's mixin into Create's ContraptionCollider.
