As the topic says, my client started using the old character models. I read somewhere that if you mess with video settings, it can reset your character models to the old ones and that's exactly what I'm doing so I think that was the cause? Anyone know of a solution to "activate" the new character models?
You'd need to download the patches again, unless they are still in your trash bin, return them. I wouldn't recommend it though, the new models causes crashing here and there.
