Known Issues

• Animation: Problems with Animator in 5.6.0 beta after upgrading project from 5.5.0p3 (864062)

Why does the animation known issue exist even with 5.6.0f1?
I just read release notes, it seems that the problem still exists.
Is it the candidate version?
Why is it not fixed even in the candidate version?

Following up, we erroneously were keeping that known issue in.

From the developer:

The behaviour is as expected, but it highlighted a badly configured component in a sample project.

We fixed the an old bug (when Animate Physics is selected, Animator should set a velocity on animated RBs, not just teleport them every frame), and now the bus (in the bug) is moving twice. The settings on the object should be updated so that the movement is correct again.

We’ve updated the upgrade guide, and we’ll remove the known issue.
