    Thank you for the consistent updates, @RichardKettlewell! We really appreciate them, since this bug is affecting our ability to develop and patch our live game. Please let us know if the fix does fail final testing and the release date slips so we can plan accordingly.

    Thanks again!

    Hi again.

    The fix has now landed in our mainline code, which is the first step towards getting it out in a patch to you all.

    These are the following versions it should be fixed in:

    - 2019.2.0a4
    - 2019.1.0b3
    - 2018.3.5 (release date approximately 6th February)

    For 2019.1 and 2018.3, we will only hit these versions if it passes final testing in those versions. We will find that out in the coming days.

    Thank you for your patience.

    >Would be great to get an official confirmation that you guys saw the comments indicating this bug does not only affect VR projects.

    Yep, we know it's not only VR and the fix should cover all cases.

    >What do you mean by which version it will land in?? so you can't fix for all versions?

    It will be fixed in 2018.3 and above. I mean the precise patch version is not yet known as it is still in testing.

    The reason there's no mention of this bug in patch notes is because the bug hasn't been fixed yet, it's not that hard of a concept to understand. A dev replied 2 days ago saying they were testing a possible fix and would update us once ready.

    2018.3.3 was released two days ago, no mention of this bug in the release notes... This issue has by far the most votes (by a factor of x4), I wonder what process is in place that prioritizes other issues. Dear technical director, please pay attention to your users.

    I was just about to finish upgrading my project when I discovered this bug with the Particle Systems. I can confirm that this bug is present in Unity 2018.3.0f2 as it is listed as an official build, in Unity Hub, but not listed as one of the test builds being used to reproduce and track this problem. I'm working on a VR project using SteamVR. Originally I was using Unity 2017.4.1f1 but was forced to upgrade to keep up with SteamVR 2.0. Unfortunately, Unity 2018.3.0f2 is the only build that works correctly with it. I make heavy use of Particle Systems, so I hate to find this out just now. If I had known, I would've waited before upgrading.

    Hi Unity, when you could release a new version to kill this Bug?
    Even if let us first normal use let the game to the player experience, the game died, our team died, this must not be what you want to see!
