    The issue tracker says that this issue is fixed, and today Unity released 6000.0.59f2. I have read through the release notes,

    https://unity.com/releases/editor/whats-new/6000.0.59f2#installs

    And there is no mention of this being fixed in 6000.0.59f2, even though the issue is fixed in 6000.0.59f1.

    I upgraded to 6000.0.58f2 when I received the email from Unity warning of the recently found vulnerability issue with Unity, so I downloaded the new version, opened my project, and I experienced this bug immediately in my game, and then took the rest of the day to debug the issue only, to then find out this is a known bug and would be fixed in 6000.0.59f2. Great, I thought I would wait for 6000.0.59f2, and everything will be great.

    But no. :(
    No mention of this issue in the release notes for 6000.0.59f2.

    Can we get clarification as to what version this fix will be rolled into?

    Many Thanks

    I am using particle system and started seeing this error after updating from 6000.0.32f1 to 6000.0.58f2. I updated due to the security vulnerability notice.

    Plus one. I updated to the latest Unity 6.0 (6000.0.58f2) patch due to security vulnerability and I am now seeing this issue (was not seeing it before).

    I had to update from 6000.0.13f to 6000.0.17f due to a recent Vulnerability bug found on older versions. Now I am getting this error quite frequently.

    Exists in 6000.5.56, 57 and 58. It says fix in review for .59. Waiting for the fix, or perhaps revert to an older version? can't ship like this. happens in 2D URP on all particle systems in the game. Much less on .58 than previous versions but still happens.

    Try changing the particle system's simulation space to local instead of world.
