What the heck happened ??

I didn't cancel it. I didn't know my friend had gotten dropped and I was waiting for the duty to start.

Try not to worry about it overmuch. It's just a prompt to warn you of the withdrawal penalty, and it is not actually penalizing you. If your friend's connection is dodgy enough to make this happen twice; it's probably not the best idea he goes into group content anyway.
