Bug Report: Game crash when two physical objects collide (Rapier internal error)
Game version: Minecraft 1.21.1
Mod version: Sable 1.2.2
Related mods: Create Aeronautics 1.2.1, Create 6.0.10
Launcher: Prism Launcher 11.0.2
Java: OpenJDK 21.0.7
OS: Windows 11 (build 26200)
Description
The game crashes instantly when two physical objects collide (for example, when one object falls onto another).
Steps to reproduce
Spawn or create two physical objects (using Sable / Create Aeronautics physics).
Drop or move one object so that it collides with the other.
The game crashes immediately.
Expected behavior
Objects should collide normally without crashing the game.
Actual behavior
Game crashes with the following Rust panic inside the Rapier physics engine:
text
thread '' panicked at .../rapier3d/.../narrow_phase.rs:1222:34:
Internal error: island should be awake.
thread caused non-unwinding panic. aborting.
Exit code: -1073740791 (STATUS_FATAL_APP_EXIT)
Full crash log
[Attach the full log from the original post]
Additional notes
The error occurs in the Rapier physics engine (used by Sable).
The crash happens during collision detection (narrow_phase.rs).
The error suggests an internal inconsistency — a physics island was expected to be awake but was not.
Workaround
Avoid allowing physical objects to touch each other. Removing Sable prevents the crash.
Please fix this issue. Thank you!
