During the last closed beta and the open beta I had the problem several times.
During combat the attack button and dodge button would stop responding randomly.
I am relatively sure that it was not a situational misunderstanding of gamemechanics since there was one instance of the bug that lasted 10 seconds in which I was mashing L1 and Spacebar and the only response was the character wiggling with the sword up and down a bit.
Most of my mates use a controller and they never reported any similar problems. However the one that did also use mouse and keyboard reported the same issue.
I suspect that since the mouse is not locked into the center of the screen (can be seen when opening ubis new overlay which doesn't hide the mouse after closing anymore - incredibly annoying) it might be that there is either some GUI Box that prevents input or the mouse moves out of screen somewhere. Would require further testing once I found a way to lock the mouse to the screen center. I do not know how to recreate the bug since it occurs randomly and would require specific testing which is not possible as of now.
Does anybody have the same issue / is this a known issue / is there any fix for this?
I would love to have a fix before the game comes out.
