I have noticed a weird transition between normal and attack mode when casting Killer Instinct and using it for a while.
In the video below, I have performed a standing jump on wall and then I have casted killer instinct. After one or two spells, I get that immediate transition between normal and attack mode, which is bit annoying since you lose the smooth feeling of movement. Moreover, sometimes you need to tap control key twice to change attack mode during this bug.
And after the deactivation of killer instinct, you get the auto-run bug which always happens with all spells after a standing jump.
Best,
PS1. Sorry for the music background, forgot to turn it off while recording.
PS2. Still hoping that NGD will include "attack speed" attribute in the character sheet. Measured in "hits per second".
