That is some sort of bug? I don't know.
Sometimes, my character runs somewhere without a command. So he (she) just runs forward (can be a different direction) and I can't stop that. So if the character is runnig in A (SWAD) direction, I can "stop" him with D. But he keeps running when I stop pressing the button.
Steps to Reproduce
It happens randomly, I don't do anything specific. I think.
This issue has not been confirmed by a developer yet.
