If you try and make more than 8 custom tags in the txt buffer the game will crash to a white screen,than every time you try to go to a arena it will keep crashing and not load. I found that if you delete the filters.cfg file it will fix it back to normal. I copied my filters.cfg file that works but cant add any more.
