I had just finished being rushed thru normal, and went to test something out with the idea of 2x CTA on a barb (I know that they won't give more than +3 BO, but CTA gives +1 to all skills also...).
Anyway, after switching *2* characters, I get IP banned with my 2x +5 CTAs on the floor. My friend who was doing the rushing only had half a clue that I was xferring. He's not on AIM, and I couldn't get ahold of anyone else in time.
So, it's possible I may have lost my CTAs. It IS possible that my friend picked them up (don't know, he logged off before I got back on).
Thats true Voll just wait till you hear for sure from your friend before thinking the worst.Like u said if he had some idea what you were doing he may have jumped into the game if he saw the message your friend has exited battle net.
