The controller button input trigger is missing, and unable to perform special attacks/skills with the controller (Yes The special interaction is already set up), even some time the CUB skill controller input trigger button UI also disappears, it should be show up when using Controller like the blue mark at the picture (CUB skill is still able to accomplish with the controller)
the only way can trigger the special attack is trigger by mouse clicking, it makes the game can't play properly. as the video shows. I hope this can be fixed and optimised.
