CharacterController might start to ignore collisions after a scene was reloaded more than 85 times



Steps to reproduce:
1. Open attached project
2. Open "Test" scene
3. Run the scene
4. Notice how "Instance {number}" fails to collide with "Character(Clone)" (gif attached)

Note: a lot of instances are created and if all succeed scene is loaded once again until a failure.

Does not reproduce on OSX.

Does not reproduce on Windows when number of attempts is less ~85.
Does reproduce on Windows when number of attempts is above ~85.

Reproduced with: 5.2.4f1, 5.3.3p3, 5.3.5p5, 5.4.0b24, 5.5.0f3

    FWIW: Rolls out with 5.5.4p2 scheduled for mid July. Unless high demand, there won't be a back-port to earlier versions. Anthony.

    @UNCADE - there will be a 5.6 back-port, as well as a likely 5.5 fix later on. I can't share the dates as of yet though. Encourage you to watch this thread, there will be an announcement as soon as I confirm the version/date. Thanks.

    Is there going to be no fix for 5.6?
    If so that is extremely disappointing, as this has been an issue for the entirety of Unity 5.

    Back-port will be available as part of 2017.1 beta 10.

    Which release will this fix be available in? Will it be ported back to 5.6?

    (Well at least I think I fixed it, I need Anthony to try the fix and confirm :) Fingers crossed)
