I went into a mission to help a friend and I kept noticing the the blue affect and sound that plays when you spend energy on a gate or reviving periodically happening. I though nothing of it thinking it was a graphics bug. Later in the first floor I realized it was spending energy every time that happened. In the course of one floor (no revives or gates bought) it went through all my mist and almost 100 ce. I tried to return to haven when I saw what was happening but halfway through havens loading screen, I would be redirected right back to the spot in the dungeon I was trying to leave. Eventually I just terminated the games process. I was just wondering if this is a bug or something I just didn't know about, like if it is a fee to help some one complete a mission he/she wouldn't be able to do alone. halp plz?
