So i'm not sure if this is a bug or i'm just a noob. When i use the rogue ability crippling strike or the similar ability from the ranger class  crippling? shot after multiple uses the icon turns green and it says "ability already activated" and i can't use it anymore. Resting doesn't help either. It turns green even if i have still uses left.

 

Do i have to do sth. to get the abilities back or is this jsut a bug?

Nope lots of people are seeing this.  The only thing I have heard that "might" fix it is literally getting the rogue killed on purpose then when she gets back up it is supposed to be normal again.

I had something similar happen. After awhile both my rogue and fighter's modal abilities and even per rest abilities are impossible to get back after a rest or even a quit and re-load.
