Colliders are not updating to match attached gameObject location

Physics

-

Colliders are not updating to match attached gameObject location. After their object is stored and returned from a pool (reparenting, deactivating and re-activating the gameObject in the process) they become stuck at the location they were at when first activated. The collider gizmo does not reflect this.

To reproduce:

1. Download attached project "WoP Bugreport.zip" and open in Unity
2. Open "bug_example" scene and enter Play mode
Note: Enable gizmos in the game view for better visual cues to raycasting
3. Using a gamepad navigate the player character to the weapon on the ground and pick it up using the 'B' button (XBOX controller)
4. Use the 'X' button (XBOX controller) to fire the weapon at the enemy, killing them and causing them to return to the pool.

Notes:
- The enemies spawn one at a time from a pool of 10 total.
- After the 10th enemy has been dispatched they will start recycling. At this point observe that both the aim assist feature and the collision of projectiles confirm the enemy's collider remains at their initial spawn point as they move about.
- By selecting the enemy in the hierarchy and disabling/enabling their sphere collider, observe that it moves to the latest position of the game object but does not update.
- Workaround: By adjusting any property of the sphere collider, observe that the collider now begins to follow the game object as would normally be expected
- This issue appears on Unity Editor and Standalone Build

Reproduced on Unity 2017.2.0f3 and 2017.2.0p1
Not reproduced on Unity 2018.1.0a2
Could not check for regression on Unity 2017.1 and 2017.3 because XBOX Controller does not work for some reason

    Anyone still seeing this issue, you might need to: project settings -> physics -> auto sync transforms -> tick.

    Otherwise your collider positions might not be updating to reflect the position of their transform. For me this was the issue because I was not using the physics engine for anything but raycasts. Therefore the collider positions were not being updated as part of the general physics update. Hope this helps. :)

    Getting a similar issue on 2019.3.6f1.

    Colliders seem to be lagging behind the actual transform position when I move the gameobject.

    2019.2.9f1: This issue was driving me nuts. Updating the centre of the Collider resolved it. Odd to read that it's not reproducable.

    I suspect I am stumbling into the same issue right now with 2019.3.f5. It seems somehow like the colliders are not updated at the same time as the game object is resized but slightly later. I am not at the bottom of the issue though yet.

    Still having the same issue in 2019.3 and yet his issue is closed and marked as resolved? For some reason colliders don't update when you move the gameobject, but stay in their original spot.

    I still have the issue where if I scale a game object with a collider on it. The collider stays at the same size. I'm using unity 2019.2.0f1. Not sure why we can't vote for it even if it's not reproducible. If we still have the issue, we should still be able to vote...

    I'm having the same problem on unity 2019.2.6f1
    What should I do ?
