I have an alias for the practice that practices a skill ten times. I set my spam to forty prac times, then check the skill so I can surf while I spam and know when I need to enter the prompt again. It looks something like cam1;cam1;cam1;cam1;skills camouflage. I input that about 60 times standing in different rooms, different terrains. Oddly, I gained a level and then it started learning the skill. Don't know if something was changed or what. Really fucking frustrating, though.
