Game Studio crash when copying a collider

[w0wca7a]

Release Type: GitHub

Version: master

Platform(s): Windows 10 19045.5965

Describe the bug
It seems copying and replacing colliders in Game Studio is impossible

To Reproduce
Steps to reproduce the behavior:
In Game Studio

1. Add Entity to Scene
2. Add model component and model to Entity
3. Add BepuPhysics Character component to Entity
4. Add two capsule colliders to Compound colliders list
5. Configure first collider then copy Item0 and paste or replace to Item1

Expected behavior
Successful copying configured collider to another one

Thanks for reporting.

The definition of property Collider in CompoundCollider is problematic. It cannot work as-is with copy/pasting.

The property likely need to be a flat List (instead of an internal type), or have a dedicated copy/paste processor.
