In case you don't know, Patch v21.00 (the release of Ch3s3 in the other mode) has created a bug that causes players to have animation issues. Examples can be seen here:
As you can see, slow animations of the characters, it can also slow your movement speed down with or without a speed melee weapon, it can also cause heavy attacks with melee weapons to stop working. It happens at these scenarios:
Intense missions like Eliminate And Collect in mid to high end of the game.
4 player defense missions at any power level.
Defense missions at high end (except repair the shelter)
Possibly some run and gun missions like Destroy The Encampments.
Most noticeable at older gen devices (PS4, Xbox One X / Xbox One S, Several old PCs). I consider it a critical bug for now due to it affecting some gameplay aspects.
