I'm sorry. I changed the visibility because I thought you had already found the issue. I had already modified the code to not cause a compiler error.

Thanks for making it public again.
Here is a reduced example of the ICE: https://github.com/cyrgani/rustc-ice-version-conflict
The issue why the compiler panics is that rapier depends on bevy 0.14, but the game crate depends on bevy 0.15. When importing a type from rapier in game, the ICE occurs.
