I have just released a new patch on the Test Server with several improvements to the Movement System.
What this changes is that characters should now try to avoid each other instead of going through, more or less replicating the old behavior (without the spin).
Improvements have also been made regarding the Movement prediction, which should reduce the amount movement of rollbacks players with high latency were experiencing.
Finally, the animation bug where characters were sliding should be fixed, at least for your own character. Let me know if it still happens with other characters.
