Environment

  • Minecraft 1.20.1
  • Forge 47.4.6
  • L2 Complements 2.5.7
  • L2 Library 2.5.3
  • Patchouli 84.1
  • L2 Hostility 2.5.9
  • GregTech Modern 7.1.4
  • JEI 15.20.0.112

Expected Behavior:

Multiblock structures should render correctly, as shown in the following screenshot:

Additional Information:

The crash appears related to the interaction between LDLib’s(which is built in GregTech) virtual world rendering and L2Hostility’s chunk capability initialization. It specifically affects GregTech multiblock structures preview.

Moreover, in other cases when gt load its 3d
preview (like in the machine gui), the game will crash.

Looks like it triggered L2H's chunk difficulty initialization and L2H asking for world height causing the crash. Can be fixed by GregTech returning a dummy value (let's say, 16) for world height
