CreateWindmillFix

Create Axis Fix is a small compatibility/fix mod for Minecraft 1.21.1 with NeoForge and Create 6.0.10.

This mod fixes a crash in Create’s ContinuousOBBCollider system where the collision axis or normalAxis can sometimes be null. When this happens, the game or server can crash during Create contraption collision calculations, for example when moving Create machines, rotating contraptions, or using mechanical blocks that interact with collision logic.

Features:
- Fixes crashes caused by null axis values in Create’s ContinuousOBBCollider.
- Adds a safety check so missing collision vectors are replaced with Vec3.ZERO instead of crashing.
- Helps servers and modpacks stay more stable when using Create contraptions.
- Works on both client and server.

How it affects gameplay:
This mod does not add new blocks, items, recipes, mobs, or gameplay mechanics. Instead, it improves stability for players using Create by preventing a specific crash related to contraption collision calculations. Players can continue using Create machines and contraptions without the world or server crashing from this known issue.

This mod is useful for modpacks or servers that use Create 6.0.10+ and experience crashes involving ContinuousOBBCollider, axis, normalAxis, or Vec3 null errors.
