I've gotten attached to one of my followers. Unfortunately, she's capped at lvl 30 according to the wiki which means not even the disable/enable trick will work. I'm already lvl 40 and her inability to keep up is starting to show. Is there any way to increase the max level of your followers?
I wouldn't be surprised if there was a way, but I don't know it. As an alternative, you could use the "Setav" console command. Eg. "Setav Health 600" would set the target's health to 600", this works for skills as well obviously (except the limit for skills is presumably 100).
