I signed up to the forum to post this exact same thing. I absolutely love Risk of Rain - and I haven't had so much co-op fun in ages. Unfortuntely though I get the same problem, and it is really saddening, it makes me not want to play the game at all. I can have a great game and unlock a bunch of items and new characters, but then the game crashes on maybe the 4th or 5th teleporter, and of course I lose all the progress I've made. It's so frustrating! I don't know if this is related or not, but the music and some of the sounds cut out after a couple of levels as well. I can live with that, but I really, really can't live with the game crashing without fail every 4th/5th level The game reallyneeds a patch for various other small issues, but this one is really a game-breaking issue. I'm sure you're working on fixing it...I just really hope you can soon, before my friends (who don't have the crashing problem) play too much and get sick of the game!
