For the past few days me ED abilities have been very chaotic in when and if they work.
Today it spread to PRE abilities. Most of the day I couldn't assassinate anything. my DC's are fine (48). I had to TCB so I didn't get to investigate why.
Then when I switched to my other assassin it started working.
Now I'm back on the former and assassinate is working fine but ED abilities are screwed up again. I can't get a charge at all.
