Hello,

I have one persistent ObiSolver and an instantiated prefab which contains several ObiColliders. When I change the prefab during the game (i.e destroy old prefab and instantiate new one in a single frame), sometimes the collisions for new prefab are not working and I got these errors:

Code:
System.IndexOutOfRangeException: Index {0} is out of range of '{1}' Length.
Thrown from job: Obi.BurstColliderWorld.IdentifyMovingColliders
This Exception was thrown from a job compiled with Burst, which has limited exception support.

Hi there,

I've performed several tests regarding this use case but I can't reproduce this error. The internal collider arrays are updated right at the start of every simulation step, so it shouldn't matter if you add/destroy prefab colliders at runtime.

Could you send a repro scene/project to support(at)virtualmethodstudio.com so that I can take a look at this?

kind regards,
