You're my hero, really. Staying in the editor for so long... That's what I call dedication!
Well, what the heck else is there to do when you can't play the actual game anymore?
Back when I first started playing City of Heroes, I used to have a lot of connection problems with my internet, but I noticed that if I was in the costume creator when the internet went down, I never got booted off. Sometimes I spent hours creating costumes just waiting for the internet to come back. If I backed out to the server selection or tried to enter the game, I got logged out, but otherwise I was good. So that's how I knew the costume creator would keep working as long as I logged in before the servers turned off.
Now I'll have to see how long I can keep it going.
