I've had this bug too for days and it is by far the most irritating bug I've discovered so far in the game. I submitted a bug report days ago but no one's bothered to reply. I would have thought they could have fixed this by now what with the servers being taken down every day for maintenance now.
Unfortunately they seem to be too busy making this game a nuisance by making it more and more difficult.
Remember, this is not meant to be fun, it's meant to be a challenge! You don't need stupid costumes to make the game a challenge
It's really sad. CoH is a wonderful game, because you can play it at different difficulty settings and everybody can have fun. It also gives you a lot of customization options. I had the illusion they would make an other great game like this.
Now their only fear seems to be that people level too fast.
