Description

MoreCulling 1.3.0’s mixin for AbstractBlockState.customCullingShape runs before the model manager is fully initialized when ViaFabricPlus’s target version has been modified, causing a NullPointerException in combination with ViaFabricPlus 4.1.2.

Reproduction Steps

1. Install Minecraft 1.21.5 + Fabric 0.16.14 + Fabric API 0.121.0 + Cloth Config API 18.0.145 + MoreCulling 1.3.0 + ViaFabricPlus 4.1.2.
2. Launch the game once—initial startup completes fine.
3. Change ViaFabricPlus’s target protocol version to 1.21 - 1.21.1.
4. Exit the game.
5. Relaunch the game—crash occurs in initShapeCache.
